The number of bright stars in the Big Dipper bucket. How many stars are there in the constellation Ursa Major. How many stars are in Ursa Major? Seven stars of the big dipper

The most conspicuous and well-known constellation to all, without exception, is, of course, Ursa Major. More precisely, it is not she herself that is clearly visible in the night sky, but part of her - the Big Dipper. If you look closely, then below and to the right of it you can see a few more stars that make up the paws and head of the Bear. The shape of this constellation is really very fascinating. After all, no one has ever seen bears with such long tails.

The number of bright stars in the Big Dipper bucket is clear to everyone. There are exactly seven of them. The name of these stars was given by Arab astrologers in the Middle Ages.

To our ears, their "names" sound really strange:

• Merak.
• Mizar.
• Fegda.
• Megrets.
• Dubge.
• Aliot.
• Benetnash.

From the earth, these stars appear equidistant. In fact, this is far from the case. The number of bright stars in the Ursa Major bucket is seven, and they are all not at equal distances from the Earth and the Sun.

Closest to our planet is Benetnash. The farthest star, Alioth, is sixty light-years away. However, it looks brighter than Benetnash. This is the brightest and most brilliant object of the Bucket. According to the apparent intensity of the emitted light, all the stars of this part of the Big Dipper are close to the stars of the 2nd magnitude.

Noteworthy Facts

If you look very closely at one of the stars of the Bucket - Mizara, you can see a faint flicker right next to it. This is explained very simply. Mizar is not an ordinary star, but a double one.

The facility located right next to it is called Alcor. From Arabic, these two words are translated as "Horse" and "Rider". Alcor and Mizar are one of the most visible double stars from Earth.

The number of bright stars in the Big Dipper bucket is seven. However, if you look at it through binoculars or a telescope, you can see two more small strokes of light. Unlike stars, they look fuzzy and blurry. This is how distant galaxies look from Earth. Located inside the Ursa are called Whirlpool and Pinwheel.

Rotation of the Huge Bucket

The fact that our Earth does not stand still is clear to any schoolchild. Due to its movement, it seems that the stars in the sky are spinning. The Bucket is no exception in this regard. In winter and autumn, Ursa Major is located in the northern part of the night sky, not too high from the horizon. In spring and summer, this most conspicuous constellation can be seen almost at its zenith. And at this time of the year, Ursa Major looks upside down.

celestial compass

So, the number of bright stars in the Big Dipper bucket is exactly seven. Two of them can serve as a guide for those who are on the road. The fact is that it is easy to detect the most famous star in the world - the Polaris. It's easy to do. It is only necessary to draw an imaginary line along the two outer stars of the Ladle bowl. Further on it should measure approximately the distance between them. The North Star itself is located almost above the northernmost pole.

In ancient times, when there were no navigational instruments yet, it specifically served as a guide for all sailors and travelers. So, if you suddenly find yourself in a difficult situation in an unfamiliar area - look at the constellation Ursa Major. The polar star found on it will show you the way to the north. This small and not too bright celestial object has more than once rescued those lost in the taiga, in the desert or in the sea. The North Star leads the nearest neighbor of Ursa Major - Ursa Minor. The area of ​​​​location of both these "animals" is considered circumpolar according to the systematization of astrologers.

How many stars are in the Big Dipper

Of course, in this constellation itself there are even more stars than in its most conspicuous part - the Bucket. At the moment, there are about 125 of them. These are over a hundred bright objects, against which the Sun would look like a small and dim luminous dot. The closest star to Earth, unfortunately, is not even visible to the naked eye. She also does not have a name. According to astronomical systematization, it passes as a star of 7.5 m. The light from it to the Earth takes about 8.25 years. This is almost twice as much as from the closest star to us - Alpha Centauri. Thus, the answer to the question of how many stars are in Ursa Major is simple - more than a hundred and not all of them are visible without a telescope or binoculars. To see a feral animal with a long tail in the Bucket, you actually need to have a fairly rich imagination.

Legend of the Big Dipper

Of course, about such conspicuous objects of the night sky as the stars of the constellation Ursa Major, there simply cannot but exist many different kinds of myths and legends. The most popular legend about her was invented by the Greeks. The chroniclers of this old country say that once the king of Arcadia had an unusually beautiful daughter, Callisto. And this woman was so proud of her attractiveness that she dared to compete with Hera herself, the wife of Zeus. The enraged goddess, using her mystical power, of course, took revenge on the proud woman, turning her into a bear. The son of Callisto Arcas, who was returning from hunting at that time, saw a feral animal at the door of the palace and decided to kill him. However, at the last moment he was stopped by Zeus, who was not indifferent to the beauty. After the rescue, Callisto was raised to heaven. The stars of the Ursa Major bucket are what it is. At the same time, the supreme god raised the beauty’s beloved dog to heaven. Now it is known under the name Ursa Minor.

nearest constellations

The stars in the constellation Ursa Major, or rather in its Bucket, are the most noticeable in the night sky. However, in addition to Ursa Minor, there are several more recognizable constellations in this area. The reference point for finding one of them can be the same Polar Star. Behind her, on the opposite side from the Big Dipper, at approximately the same distance, Cassiopeia, familiar to many by name, flaunts. From the outside, this constellation looks like the Russian letter "M". At some positions of the Earth, Cassiopeia "turns over" and takes the form of a Latin W.

Between it and Ursa Minor, you can see the not so noticeable, but also the notorious constellation Cepheus. It does not have a clearly visible form. Between Ursa Major and Ursa Minor, it is also easy to see a wriggling Dragon. The chain of its stars is easily connected on the map by a broken line.

Well, we hope we have answered the main question of the article about how many luminous permanent objects there are in Ursa Major. There are only seven of them in the Bucket. The main constellation contains about 125 distant "suns".

How many stars are in Ursa Major?

Ursa Major is a large server constellation. The seven main bright stars of the constellation form the well-known and famous bucket. The constellation Ursa Major contains 210 stars visible to the naked eye.

There are only 7 stars in the constellation Ursa Major.

They are arranged in the shape of a bucket.



Once the constellation Ursa Major was called Seven Wise Men

Seven Stars:

1. Star Benetas
2. star Aliot
3. star dubhe
4. star Merak
5. star Fekda
6. star Megrets
7. star Mizar

There is a legend that the North Pole - the Arctic was named after the constellation Ursa Major.

The ancient Greeks called her Arkos, hence the word arctic - Arctic.

Constellation Ursa Major is a very important constellation. It is easily located in the sky and helps to find the Polar Starquot ;. Therefore, it is important for every person to know where he is and how many stars are included in the constellation Ursa Major. These are seven stars, namely: Benetash, Aliot, Dubhe, Merak, Fekda, Megrets, Mizar.

Dear chela, no one can accurately and unambiguously answer your question. And the point is not only that not a single stellar astronomer knows the exact answer, but also that the number of observed stars will depend, figuratively speaking, on the chosen frame of reference. If we observe in a large city, for example, such as Moscow, through its dusty and light-polluted atmosphere, then it is good if we can see a dozen of the brightest stars in this constellation. Observing the constellation somewhere on the western border of the Moscow region, an observer with keen eyesight will be able to see stars up to about the sixth magnitude (6m). And the total number of stars that he can observe in the constellation Ursa Major will be about 120. If this observer observes the constellation, being at a point with a wonderful astroclimate, for example, somewhere in Hawaii, near the Mauna Kea observatory, at an altitude above 4000 meters, then he will be able to see stars up to 7m without instruments. In this case, the number of stars observed with the naked eye in the constellation Ursa Major will be approximately 240-250. But a record number of stars in the constellation Ursa Major can be seen in the Palomar Sky Atlas. It registered objects up to 21m. And these are not only the stars of our Galaxy, but also a huge number of other galaxies and their clusters. But different galaxies contain from tens of millions to hundreds of billions of stars. So it is almost impossible to count all the stars that are within the boundaries of the constellation Ursa Major.

And, sorry, I'll correct you a little. Polaris is the alpha of Ursa Minor.

One of the most beautiful and most recognizable constellations in the northern hemisphere of the sky is the constellation Big Dipper. On a clear night, seven main stars stand out brightly, but in fact, 125 can be distinguished with the naked eye. There are many double stars in the constellation. The most famous, by which visual acuity is determined, is Mizar and Alcor what does Horse and Horsemanquot ;.



But the North Star is part of Ursa Minor.

Big Dipper- one of the most famous, most noticeable and largest constellations of the sky. It is especially well observed in the northern hemisphere, as it belongs to the circumpolar constellations (it can be observed all year round, especially part of the constellation - the Big Dipper).

There are a huge number of stars in the constellation Ursa Major.

If we talk about the Big Dipper (as part of the constellation), then the most noticeable to the naked eye are 7 stars that make up the handle of the bucket and the bucket itself. It is noteworthy that the middle star of the bucket handle is a star Mizar is a double star (together with a less noticeable rider - a star Alcor. Therefore, it is worth talking about 8 stars of the Big Dipper. Although there are actually many more stars in the constellation.

In the Big Dipper seven stars. By their arrangement, they resemble a large bucket with a handle.

Moreover, each star in this constellation has its own name:



Three names can be seen in the picture:

• Benetash (translated from Arabic means the leader of the mourners),
• Aliot (translation unknown)
• Dubhe (translated as bear).

The rest have the following names:

• Merak (?) translates as loins,
• Fekda (?) in the translation of the thigh,
• Megrec (?) means the beginning of the tail,
• Mizar (?) is translated as a sash.

• I remember, sitting at an astronomy lesson, the teacher told us about this or that constellation. A separate lesson was about the Big Dipper. They told me where to look, where exactly to look. Separately, they forced me to write in a notebook the stars that are in the Big Dipper.

  Benetash, Aliot, Duhbe, Merak, Fekda, Megrets, Mizar.

  These are the school times =) It was interesting

  And it's good that there were no control tests in astronomy

  And so much knowledge ... =)

  If we talk about the stars that make up the constellation Ursa Major, then there are exactly seven of them, you should not count double stars as two, since they still cannot be separated by an eye. In extreme cases, you can consider the eighth star of the constellation the star Alcor, which is seen next to Mizar. in ancient times, this pair of stars was called a horse and a rider, and it was believed that a person who was able to see Alcor had excellent eyesight. If we count the stars that are located and can be observed in the area occupied by the constellation Ursa Major, then there are really a lot of such stars. The constellation includes more than 200 stars that can be seen with a simple telescope. And how much you can see through the Herschel telescope is scary to even imagine. But still, I repeat, the constellation itself is formed by only 7 stars.

  

  A person with normal vision can see about a hundred stars. With the help of instruments, you can see thousands of stars. The constellation also includes the stars of galaxies, in which there are also many thousands of stars. And how many stars do we just not observe? And there are seven stars in the bucket, one of them is double.

Ursa Major (lat. Ursa Major) is a constellation in the northern hemisphere of the sky. The seven stars of Ursa Major make up a figure resembling a ladle with a handle. The two brightest stars, Aliot and Dubhe, have magnitudes of 1.8 apparent magnitudes. According to the two extreme stars of this figure (α and β), you can find the Polar Star. The best visibility conditions are in March-April. It can be seen throughout Russia all year round (with the exception of the autumn months in southern Russia, when the Big Dipper descends low to the horizon).

Detailed description

The constellation Ursa Major is located in the northern hemisphere of the starry sky.. People have known it for thousands of years. The astronomers of Egypt, Babylon, China and Ancient Greece knew him. It was included by Claudius Ptolemy in his monograph Almagest as early as the 2nd century. And this work combined all the knowledge of astronomy at that time.

The Big Dipper is formed by the following seven stars:

1. Dubhe (Alpha Ursa Major), the name comes from the Arabic expression - "the back of a big bear."
2. Merak (β) - from Arabic "loin" or "groin"..
3. Fekda (γ) - "thigh".
4. Megrets (δ) - "base of the tail". It is the dimmest star among the stars of the Big Dipper.
5. Aliot (ε) - "fat tail". The brightest star in this constellation.
6. Mizar (ζ) - from Arabic - "belt". Near Mizar there is another star - "Alcor". It is noteworthy that the ability to distinguish between these two stars is a consequence of good vision (with myopia no more than 1 diopter).
7. Benetnash (η) or otherwise - Alkaid. The third brightest star in Ursa Major. "Al-Qaeed banat ours" is translated from Arabic as "the leader of the mourners."

As you can see, this formation includes 7 stars. If you connect them with a straight line, you get a figure that resembles a bucket with a handle. Each star has its own name. At the top of the bucket, opposite the handle, there is a star called Dubhe. It is the second brightest among its cosmic counterparts. This is a multiple star. That is, several stars from the Earth are seen as one due to the close distance to each other.

In this case, we are dealing with 3 stars. The largest of them is a red giant. That is, the core has already lost all its reserves of hydrogen, and a thermonuclear reaction is taking place on the surface of the star. It dies, and over time should turn into a white dwarf or become a black hole. The other two stars are Main Sequence stars, that is, the same as our Sun.

On the same straight line with Dubhe, at the base of the bucket, there is a star Merak. This is a very bright light. It is 69 times brighter than our Sun, but due to the vast space it does not make the proper impression. If the straight line between Merak and Dubhe is extended towards the constellation Ursa Minor, then you can rest against the North Star. It is located at a distance that is 5 times the distance between the indicated luminaries.

The other lowest point of the bucket is called Fekda. This is a Main Sequence star. The upper point of the bucket opposite it is called Megrets. She is the dullest in a friendly company. This star is almost 1.5 times larger than our star and 14 times brighter.

There is a star at the beginning of the handle Aliot. It is the brightest in the constellation Ursa Major. Among all the visible stars in the sky, it ranks 33rd in brightness. From the end of the handle, it is the third in a row, and the second is a star. Mizar. Next to it is another luminary, which is called Alcor. Anyone with good eyesight can see it. They say that in ancient times, Alcor was used to test the visual acuity of young boys who aspired to become sailors. If a young man could see this star next to Mizar, then he was enlisted as a sailor.

In reality, not 2 stars, but as many as 6 shine in the space distance. These are the double stars Mizar A and Mizar B, as well as the double star Alcor. But from the Earth, with the naked eye, only a large bright dot and a small one, which is nearby, are visible. These are the surprises sometimes presented by space.

And finally, the most extreme star. It is called Benetnash or Alkaid. All these names are taken from the Arabic language. In this case, the literal translation means "the leader of the mourners." That is, the al-qaid is the leader, and our banat is the mourners. This luminary is the third brightest after Aliot and Dubhe. It ranks 35th among the brightest stars in the sky.

Other objects of Ursa Major

In addition to the Big Dipper, in the constellation Ursa Major, you can also observe an asterism called "Three Gazelle Jumps", which looks like three pairs of stars.

These are the following couples:

1. Alula North South (ν and ξ),
2. Taniya North and South (λ and μ),
3. Talita North and South (ι and κ).

Near Alupa Severnaya is a red dwarf called Lalande 21185, which is elusive to observe with the naked eye. However, it is the sixth closest star system to the Sun. Closer than the stars Sirius A and B.

Observational astronomy enthusiasts are well aware that this constellation contains the galaxy M101 (called the Pinwheel), as well as the galaxies M81 and M82. The last two form the core of what is probably the nearest group of galaxies, located at a distance of about 7 million light years. Unlike these distant objects, the astronomical body M 97 ("Owl") is located within the Milky Way, hundreds of times closer. The Owl is one of the largest planetary nebulae.

In the middle, between the first and second "gazelle jump", with the help of optics, you can see a small yellow dwarf, similar to our Sun at number 47. From 2000 to 2010, scientists discovered three exoplanets, gas giants, revolving around it. Also, this star system is one of the most similar to the solar system and takes 72nd place in the list of candidates for the search for planets similar to Earth, conducted as part of the planned NASA Terrestrial Planet Finder mission. So for an astronomy lover, the constellation is of great interest.

In 2013 and 2016, two of the most distant galaxies from us were discovered in the constellation, respectively z8 GND 5296 and GN-z11. The light of these galaxies, recorded by scientists, was 13.02 (z8 GND 5296) and 13.4 (GN-z11) billion years.

This is how you can characterize the constellation Ursa Major, known since ancient times. This space region also includes many galaxies. For example, the Pinwheel galaxy. It is better known as M 101. In size, it exceeds the Milky Way. Her detailed pictures were taken by the Hubble telescope at the beginning of the 21st century. To get to this huge cluster of stars, you need to spend 8 million light years.

The Owl Nebula is also of interest. It enters our galaxy and looks like 2 dark spots located side by side. In 1848, Lord Ross considered these spots to be like the eyes of an owl. That's where the name came from. This nebula is about 6 thousand years old, and it is located at a distance of 2300 light years from the solar system.

But the most interesting thing is that the constellation Ursa Major is considered as one of the likely sources of extraterrestrial intelligence. In this part of space there is a certain star named 47UMa. It is a yellow dwarf, and its planetary system is very similar to our solar system. At least, today 3 planets are known that revolve around this star. In 2003, a radio message was sent to him. Earthlings are persistently looking for brothers in mind, and luck always accompanies the stubborn.

How to find the Big Dipper in the sky?

If you want to learn how to navigate the starry sky, then your primary task is to be able to find the Big Dipper bucket. Although it is not far from the North Star, it is still not so close to it as to be at the same point in the sky all the time.

The Big Dipper is easiest to spot in autumn and winter. At this time, in the evenings, the asterism is located in the north, not high above the horizon and in the position we are used to.

By the end of winter, the position of Ursa Major in the evening sky changes. The seven stars of the bucket move to the east, and the Big Dipper itself stands upright on the handle.

There is nothing surprising. Recall that every day all the stars describe circles around the pole of the world, thereby reflecting the rotation of the Earth around its axis. But during the year, the stars make one more additional circle, thereby reflecting the movement of the Earth in orbit around the Sun. The stars of the Big Dipper are no exception - shifting from the bottom point, the bucket, as it were, rears up.

In the middle of spring, Ursa Major is at its zenith in the evenings, right above your head! At this time, he is in an inverted position in relation to the North Star. Her bucket faces west, and the handle of the bucket faces east.

For those who live north of Moscow, it is most difficult to find the Big Dipper in the sky in the summer, during the period of short nights. At this time, the constellation is in the west, and the bucket is tilted down and looks north.

How to find the North Star in Ursa Major?

Now let's see how to find the North Star using the Big Dipper. This is done simply. Take the two extreme stars in the bucket, Dubha and Merak (alpha and beta Ursa Major) and mentally connect them with a line. And then extend this line five times the distance Merak - Dubhe.

You will see a star whose brightness is approximately equal to the brightness of the bucket stars. This is the famous Polar Star, the "iron nail", as the Kazakhs called it, referring to the immobility of the Polar Star in the earth's sky.

Knowing the position of the North Star, you can easily navigate in space. Draw a plumb line from Polar down. The place where it intersects with the horizon will point north. The rest of the cardinal directions are easy to find: the east will be on the right, the south behind, and the west on the left. So, guided by the stars, in Russia in the Middle Ages they built roads Moscow - Yaroslavl and Moscow - Vladimir, straight as an arrow.

Secrets of the constellation Ursa Major: how different peoples saw it

Egypt "Bull's Thigh"

The ancient Egyptians were among the first astronomers in history, with some of their round stone "observatories" dating as far back as the fifth millennium BC. It was the Egyptians who laid the foundations for that system of constellations, which was borrowed from them by the inhabitants of Mesopotamia, Greeks, Arabs, and then modern science. At that dizzyingly distant time, due to the precession of the earth's axis, it was not the Pole Star that pointed north, but Alpha Draconis (Tuban). Its environs, together with the nearest luminaries, were considered by the Egyptians to be the "fixed sky", the dwelling place of the gods. Instead of a ladle, the priests could see the leg of Set, the god of war and death, who turned into a bull and killed Osiris with a blow of a hoof. Falcon-headed Horus cut off his limb in retaliation for the murder of his father.

China "Emperor Shandi Carriage"

The astronomers of ancient China divided the sky into 28 vertical sectors, "houses" through which the Moon passes in its monthly journey, as the Sun in its annual rotation passes through the signs of the Zodiac in Western astrology, which borrowed the 12-sector division from the Egyptians. In the center of heaven, like the emperor in the capital of the state, the Chinese had the North Star, which had already taken its usual place by that time. The seven brightest stars of Ursa Major are in honorable proximity to it, within the Purple Fence - one of the three Fences surrounding the palace of the "royal" star. They could be described as the Northern Dipper, whose orientation corresponds to the season, or as part of the carriage of the Heavenly Emperor Shandi.

India "Seven Wise Men"

Observational astronomy in ancient India did not develop as brilliantly as, say, mathematics. Her ideas were greatly influenced by both Greece and China - for example, 27-28 "stays" (nakshatras) through which the Moon passes in about a month are very reminiscent of Chinese lunar "houses". The Hindus also attached great importance to the North Star, which, according to experts in the Vedas, is the abode of Vishnu himself. The asterism of the Bucket located under it was considered the Saptarishas - the seven sages born from the mind of Brahma, the forefathers of the world of our era (Kali Yuga) and all those living in it.

Greece "Bear"

Ursa Major is one of the 48 constellations listed in Ptolemy's star catalog around 140 BC, although it was first mentioned much earlier, in Homer. Intricate Greek myths offer different backgrounds for its appearance, although everyone agrees that the bear is the beautiful Callisto, the companion of the hunting goddess Artemis. According to one version, using his usual tricks with reincarnation, the loving Zeus seduced her, provoking the wrath of both his wife Hera and Artemis herself. Saving his mistress, the Thunderer turned her into a bear, who wandered in the mountain forests for many years, until her own son, born of Zeus, met her on a hunt. The supreme god had to intervene once more. Preventing matricide, he raised both to heaven.

America "Great Bear"

It seems that the Indians understood something about wild animals: in the legend of the Iroquois about the origin of asterism, the “heavenly bear” does not have any tail. The three stars that form the handle of the ladle are three hunters chasing the beast: Aliot draws a bow with an arrow embedded in it, Mizar carries a cauldron for cooking meat (Alcor), and Benetnash carries an armful of brushwood to kindle the hearth. In autumn, when the Bucket turns and sinks low to the horizon, the blood from the wounded bear drips down, staining the trees in variegated colors.

• The closest of the bright stars of Ursa Major– star Southern Alula or xi Ursa Major. This is a beautiful double star that can be separated into components in a telescope with a lens over 80mm. Both components are similar in their characteristics to the Sun and each of them also has a satellite - a cold red dwarf! The distance to ξ Ursa Major is 29 St. years. A little further away is the star θ - 44 light years from the Sun. Well, farthest from the brightest stars of the constellation is the red giant μ Ursa Major, one of the stars in the front "paw" of the Ursa. Its distance is 249 light years.
• The constellation Ursa Major is depicted on the flag of Alaska. On the flag of the White Sea Karelia, which was approved on June 21, 1918, the Big Bucket is depicted. Also, the flag with the image of the Big Dipper is used by Irish radical left organizations.
• Ursa Major can be admired during the day. This can easily be done by finding it on one of the interactive constellation maps. On the maps, you can find other large and small constellations and look at them in a big approximation.
• Needless to say, the huge constellation Ursa Major is a real treasure trove for a true astronomy lover?! In this area of ​​the sky there is a huge number of attractions available for observation in small telescopes: double and variable stars, several bright galaxies and dozens of weaker galaxies, an open star cluster and even a planetary nebula. There is no way to fit the descriptions of these objects into the scope of one article. Therefore, we decided to publish separate articles on observations of the sights of the Big Dipper.

How to find constellation Ursa Major in the northern sky: a map of the starry sky, a description with a photo and a diagram, myth, facts, Messier objects, main stars, the Big Dipper.

Ursa Major - constellation, which is located in the northern sky and from Latin "Ursa Major" is translated as "big bear".

Ursa Major in the sky is the largest northern constellation and the third in the general list. Bright stars create an asterism recognizable by all - the Big Dipper, a photo of which can be found on the site. He was known in many cultures, so many myths were created. In the second century, Ptolemy cataloged it.

Myth, facts, position and map of the constellation Ursa Major

Ursa Major is not only a large, but also a very ancient constellation, which was mentioned by Homer in the Bible. There are so many stories and fairy tales around the world. The ancient Greeks believed that we are talking about Callisto - a beautiful nymph who took a vow of celibacy in the temple of Artemis. But Zeus fell in love with her, seduced her and her son Arkas appeared.

When Artemis found out about this, she drove Callisto away. But then the angry Hera (wife of Zeus) came into play. She was so offended by the betrayal that she turned the nymph into a bear. In this guise, the girl spent 15 years living in the forest and hiding from hunters. But Arkas grew up and one day they collided. Arkas was frightened and pulled out a spear, but Zeus managed in time and sent both of them into the sky with a whirlwind. Of course, this angered Hera even more. She asked the Ocean and Tethys not to let the bear swim in the northern waters. That is why Ursa Major never sets beyond the horizon in northern latitudes.

According to another story, the punishment came from Artemis. After many years, Callisto and Arkas are captured together and go to King Lycaon as a gift. But they escape and hide in the temple of Zeus. God saves them and sends them to heaven.

There is also a completely different myth about Adastreya. She was a nymph who took care of Zeus as an infant. His father Cronus obeyed the oracle's prediction (the child will overthrow the father) and killed all his children. But Rhea (mother) slipped a stone instead of Zeus and saved the baby. Adastraya, along with Ida, fed and looked after him, and in gratitude he sent them to heaven.

The Romans called the constellation Ursa Major "Septentrio" - "seven plows of oxen", although only two of them displayed bulls, and the rest - a cart. In the Big Dipper they saw different animals: a camel, a shark, a skunk, as well as objects: a sickle, a cart, a canoe. The Chinese name the 7 stars Qiyh Sing after the government. The Hindus had 7 wise men, and the constellation is called Saptarshi.

In some Indian tales, Ursa Major depicted a large bear, and the stars were warriors who declared a hunt for him. It drops low in autumn, so it is believed that the leaves turn red due to blood dripping from the wounds of the animal.

In late American history, the constellation represented the railroad that the slaves used to find their way north. There are many songs that the liberated sang in the south, dreaming of a new life.

The main stars of the constellation Ursa Major

You could see in the photo what the constellation Ursa Major looks like in the sky, but let's study its stars and the famous asterism.

Asterism - Big Dipper

The Big Dipper is one of the most recognizable asterisms in the night sky and has been featured in many cultures. In addition, it is also useful in navigation, because it indicates the path to the North Star, which is part of the Little Dipper (Ursa Minor).

If you follow an imaginary line from Merak to Dubhe and continue the arc, you will reach the Pole Star.

In the same way, an imaginary line leads to the bright star Arcturus (Boötes) and Spica (Virgo).

Ursa Major consists of 7 stars: Dubhe (Alpha), Merak (Beta), Fekda (Gamma), Megrets (Delta), Aliot (Epsilon), Mizar (Zeta) and Alkaid (Eta).

Aliot(Epsilon Ursa Major) is the brightest star in the constellation (A0pCr) with an apparent visual magnitude of 1.76 and a distance of 81 light years. It stands at the 31st position in brightness among all stars. The spectrum resembles a Canis Alpha-2 type variable with fluctuations in spectral lines of 5.1 days.

Included in the Ursa Major Moving Group of Stars (general speed and origin). In 1869, the group was found by the English astronomer Richard A. Proctor, who guessed that all the stars of the constellation, except for Alkaid and Dubhe, share a common regular movement, heading towards a point in the constellation Sagittarius.

The traditional name comes from the Arabic word alyat - "fat tail of a sheep" (the star is in a bear's tail).

Dubhe(Alpha Ursa Major) is a spectroscopic double star (K1 II-III) with an apparent magnitude of 1.79 and a distance of 123 light years. The companion is a main sequence star (F0 V) with an orbital period of 44.4 years at a distance of 23 AU.

At 900,000 a.u. a binary system is located from the main pair, which makes the star a four-star system.

The name comes from the Arabic dubb - "bear". Not included in the Ursa Major Moving Group of Stars.

Merak(Beta Ursa Major) is a main sequence star (A1 V) with a visual magnitude of 2.37 and a distance of 79.7 light years. There is a dusty disk that occupies 27% of the earth's mass.

The star is 2.7 times more massive than the Sun, 2.84 times larger in radius, and 68 times brighter. It is a member of the Ursa Major Moving Group of Stars and is a suspected variable star.

The name is translated from Arabic as "loins".

Alkaid(Eta Ursa Major) is a young main sequence star (B3 V) with an apparent visual magnitude of 1.85 and a distance of 101 light years. It ranks third in brightness in the constellation and 35th among all stars. It is the easternmost star in the asterism. At a surface temperature of 20,000 K, it can be seen with the naked eye. Reaches 6 solar masses and is 700 times brighter. Does not belong to the Ursa Major Moving Group of Stars.

Despite its position in brightness, Bayer named it "Eta" because he named the stars from west to east. The name is taken from the Arabic phrase qā "id bināt na" sh, which means "leader of the daughters of the pier."

Fekda(Gamma Ursa Major) is a main sequence star (A0 Ve) with a visual magnitude of 2.438 and a distance of 83.2 light years. It has a gas envelope that adds emission lines to its spectrum. Age - 300 million years. It is the lower left star in the Dipper and is 8.5 light-years distant from the Mizar-Alcor system. Refers to the Moving Group of Ursa Major.

The traditional name comes from the Arabic phrase fakhð ad-dubb, "bear's thigh".

Megrets(Delta Ursa Major) is a main sequence star (A3 V) with a visual magnitude of 3.312 and a distance of 58.4 light years. 63% more solar mass and 14 times brighter. There is an excess of infrared radiation, indicating disk debris in orbit.

Of the 7 bright stars, this is the weakest. "Megrets" is translated from Arabic as "base" (the base of the bear's tail).

Mizar(Zeta Ursa Major) - a system of two double stars, located in second place from the end. The apparent magnitude is 2.23, and the distance is 82.8 light years. Became the first photographed double star. It happened in 1857 thanks to the American photographer and inventor John A. Whipple and the astronomer George P. Bond. They used a wet collodion plate and a 15-inch refractor telescope at the Harvard College Observatory. Bond also photographed the star Vega (Lyra) in 1850.

The name comes from the Arabic mīzar - "belt".

Alcor(80 Ursa Major) - visual companion for Mizar (A5V) Both stars are sometimes referred to as "Horse and Rider". The visual magnitude is 3.99, and the distance is 81.7 light years. She is also called Suha ("forgotten") and Arundhati in India. In 2009, they found a binary system.

Belongs to the Moving group of stars Ursa Major. The distance between it and Mizar is 1.1 light years.

W Ursa Major is a binary system represented by nearby stars with an orbital period of 0.3336 days. They are so close that their outer shells are in direct contact. Periodically, they outshine each other, and reduce the brightness. The apparent magnitude of the system fluctuates between 7.75 and 8.48. Spectral class - F8V.

This is the prototype for both the W variables of Ursa Major.

Messier 40(M40, Winnecke 4, WNC 4) is a binary star with fluctuations in apparent visual magnitude from 9.55 to 10.10. Located 510 light years away. It was registered in 1764 by Charles Messier, who was looking for a nebula previously reported by Jan Hevelius. In 1863, the star was discovered by Friedrich August Theodor Winnecke.

47 Ursa Major- a main sequence star (G1V) with an apparent magnitude of 5.03 and a distance of 45.9 light years. It is a solar analogue with a similar mass, slightly hotter and reaches 110% iron.

In 1996, a planet 2.53 times the size of Jupiter was found. Two more planets were discovered in 2002 and 2010.

Nu and Xi Ursa Major - "first jump"

Alula Northern (Nu Ursa Major) is a double star visible to the naked eye. The apparent magnitude is 3.490, and the distance is 399 light years. This is a giant (K3 III), whose radius is 57 times greater than the sun and 775 times brighter. The name "Alula Borealis" comes from the Arabic word al-Ūlā - meaning "first (jump)", and the Latin "Borealis" - northern.

Alula South (Xi Ursa Major) is a star system discovered in 1780 by William Herschel. It is represented by main sequence dwarfs (G0 Ve) with a combined magnitude of 3.79 (4.32 and 4.84), and a distance of 29 light years.

This is a variable star RS Canis Venichi (near binary stars with large spots created by the active chromosphere). Spots cause the brightness to change by 0.2 magnitudes.

Each of the two objects of the Xi system acts as a spectroscopic twin and is accompanied by a low-mass companion. In 1828, Xi became the first binary star whose orbit could be calculated.

Nu and Xi are the first of three star pairs, which the ancient Arabs called "gazelle jumps".

Taniya North (Lambda) and Taniya South (Mu) - "second jump"

Lambda Ursa Major is a star (A2 IV - losing mass and turning into a giant) with an apparent magnitude of 3.45 and a distance of 138 light years.

Mu Ursa Major is a red giant (M0) located 230 light years away. The visual magnitude is 3.06. It is a semi-regular variable star whose brightness ranges from 2.99 to 3.33. Accompanied by a visual companion 1.5 AU distant.

Talita North (Iota) and Talita South (Kappa) - "the third jump"

Iota Ursa Major is a star system represented by two double stars: a white subgiant (A7 IV), which is a spectroscopic binary object, and stars of the 9th and 10th magnitudes. When the B component was noticed in 1841, the two binary stars were separated by 10.7 arcseconds. Now this distance is 4.5 arc seconds. The orbital period is 818 years. The system is 47.3 light years distant from us.

Kappa Ursa Major is a double star represented by two A-type main sequence dwarfs with visual magnitudes of 4.2 and 4.4. The apparent magnitude of the system is 3.60, and the distance is 358 light years.

Muscida(Omicron Ursa Major) is a multiple star system (G4 II-III - between a giant and a bright giant) with an apparent visual magnitude of 3.35 and a distance of 179 light years. The traditional name means "snout".

Groombridge 1830- subdwarf (G8V), located at 29.7 light years. In the early 19th century, it was found and recorded by the British astronomer Stephen Groombridge (published in 1838).

At the time of discovery, it was the star with the highest proper motion. Went to third after discovering Kapteyn's Star and Barnard's Star.

It is a halo star moving in the opposite direction of the galaxy's rotation. Usually such specimens are poor in metal, because they formed at an earlier age of the galaxy. Most halo stars are located above or below the galactic plane. Age - 10 billion years. They have highly eccentric orbits and high space velocity.

Lalande 21185- a red dwarf (M2V) with an apparent magnitude of 7.520 (cannot be found without technology) and a distance of 8.11 light years. This is the fourth closest star system to ours after Alpha Centauri, Barnard's Star and Wolf 359. In 19900 years, it will approach the Sun at 4.65 light years.

This is the BY Dragon variable and is a known X-ray source.

Psi Ursa Major- an orange giant (K1 III) with a visual magnitude of 3.01 and a distance of 144.5 light years. The Chinese call him Tian Zang or Ta Zun - "extremely honorable."

Celestial objects of the constellation Ursa Major

Bode Galaxy(M81, NGC 3031) is a bright, large spiral galaxy 11.8 light-years away. Apparent magnitude - 6.94 (very popular among beginners and amateur astronomers).

The apparent size is 26.9 x 14.1 arc minutes. In March 1993, a supernova was observed - SN 1993J.

It was discovered by German astronomer Johann Bode in 1774. In 1779, Charles Messier re-identified her and added her to the catalog.

This is the largest galaxy in the M81 group (34 galaxies), located 10 degrees northwest of the star Dubhe (Alpha Ursa Major).

It interacts with the neighboring galaxies Messier 82 and with the smaller NGC 3077. Because of this, all lost hydrogen gas and formed gaseous filamentary structures. In addition, star formation has been activated, caused by interstellar gas entering the centers of Messier 82 and NGC 3077.

Galaxy Cigar(M82, NGC 3034) is an edge galaxy with an apparent magnitude of 8.41 and a distance of 11.5 million light years.

Star formation in the galactic core is 10 times faster than star formation in the entire Milky Way. M82 is also 5 times brighter. In 2005, Hubble found 197 massive star clusters in the central region.

M82 displays infrared excess and is the brightest galaxy in the sky when viewed in infrared light.

It is believed to have experienced at least one tidal collision with Messier 81 in the past. Because of this, over the past 200 million years, a huge amount of gas has entered its core and increased star formation by 10 times.

Owl Nebula(M97, NGC 3587) is a planetary nebula with an apparent magnitude of 9.9 and a distance of 2600 light years. In the center is a star of the 16th magnitude.

In 1781, the nebula was discovered by Pierre Méchain. Age - 8000 years. It got its name because it looks like an owl's eye when viewed through a telescope.

pinwheel(M101, NGC 5457) is a grand design spiral galaxy observed by the face. The apparent magnitude is 7.86, and the distance is 20.9 million light years. In August 2011, they found a type Ia supernova (an explosion of a white dwarf star) - SN 2011fe.

Pierre Méchain discovered the galaxy in 1781 and was later added to the catalog by Charles Messier. Méchain described it as "a nebula without a star, very obscure and rather large - from 6" to 7" in diameter".

It covers 170,000 light-years in diameter (70% larger than the Milky Way). Hosts a number of large, bright H II regions and hot newborn stars.

There are 5 companion galaxies: NGC 5474, NGC 5204, NGC 5477, NGC 5585 and Holmberg IV. Most likely, the grand design was created due to contact with them.

(M108, NGC 3556) is a barred spiral galaxy discovered by Pierre Méchain in 1781. We see almost the edge. It has a visual magnitude of 10.7 and a distance of 45,000 light years.

It is an isolated member of the Ursa Major Cluster (within the Virgo Supercluster). M108 contains approximately 290 globular clusters and 83 X-ray sources.

In 1969, a type 2 supernova, 1969B, was observed.

(M109, NGC 3992) is a barred spiral galaxy with an apparent magnitude of 10.6 and a distance of 83.5 million light-years. It is located southeast of Gamma Ursa Major. In 1781, Pierre Mechain found it, and after 2 years Charles Messier added it to the catalog.

In 1956, a type Ia supernova, SN 1956A, was discovered. There are also 3 satellite galaxies: UGC 6923, UGC 6940 and UGC 6969.

It is the brightest galaxy in the M109 group (contains over 50 galaxies).

NGC 5474 is a dwarf galaxy located near M101, with which it interacts. Shows signs of a spiral structure. The visual magnitude is 11.3, and the distance is 22 million light years.

Due to tidal interactions with M101, the disk shifts away from the core and activates star birth. You can explore the constellation Ursa Major more closely by using our online 3D models and telescope. For independent search, a static or moving map of the starry sky is suitable.

"The constellation Ursa Major is the first constellation from which you need to start to know the starry sky, if you have not learned how to find the Big Dipper, the starry sky for you will always remain a scattering of luminous points ..."

Rice. one Constellation Ursa Major, diagram

The constellation Ursa Major (Ursa Major) is the largest constellation in the Northern Hemisphere of the sky and the third largest angular area among all the constellations of the celestial sphere (skysphere), in addition, Ursa Major is the ancestor of the group of constellations of the same name.
Being one of the largest in area, Ursa Major directly borders as many as 8 constellations - these are Bootes, Dragon, Giraffe, Lynx, Lesser Lion, Leo, Veronica's Hair and Hounds Dogs.
Ursa Major is a non-setting constellation throughout Russia (more precisely, the main asterism of the Big Dipper constellation, which can serve as a huge night sky clock, is non-setting).

Stars and contour diagram of the constellation Ursa Major

The constellation Ursa Major is the most visible and recognizable constellation in our northern sky. In the constellation, as many as seven stars are brighter than the third magnitude - this is Epsilon Ursa Major (ε UMa, 1.76 m) - Aliot, α UMa - Dubhe, η UMa - Benetnash, ζ UMa - Mizar, β UMa - Merak And Fekda(γ UMa) with the controversial ψ Ursa Major Tai Zun(Fig. 2).

From the most ancient times, regardless of cultural and religious traditions, within this constellation, people have distinguished seven bright stars that form a schematic drawing of a bucket, which is now called " asterism Big Dipper". This asterism certainly deserves a separate image (Fig. 5), since it has another characteristic group, which requires additional magnification to show - these are visually double stars Alcor and Mizar, "rider" and "horse", respectively. There is a myth that in ancient times this pair was used to test their eyesight during the selection of warriors.
All, even not very bright stars included in the Big Dipper asterism have their own names, and received from different peoples - this is a chain of stars (starting from the handle and ending with the ladle of the ladle). All stars used to build the Big Dipper diagram are navigation stars.

After the contours and the brightest stars of the constellation have been studied to automatic recognition, you can begin to search for the constellation Ursa Major directly in the starry sky.

How to find the constellation Ursa Major

The constellation Ursa Major is usually found by its main asterism, the Big Dipper. It is best for someone to show the Big Dipper, it is enough to see this configuration of stars in the sky at least once, and it will always take shape before your eyes!
But what if there is no one to show the Big Dipper?
For the first time, the constellation Ursa Major on its own can be found as follows:

1. If you live at the latitude of Moscow, then after waiting for the month of April and going outside at about 11 pm local time, you will find the Big Dipper right above your head, at the zenith. You just have to correctly determine the angular dimensions of the bucket and mentally build its pattern according to the stars.
True, at other times of the year or if you are located significantly south of Moscow, you can’t do without a compass ...
To determine the angular dimensions, you need to know that the angular distance from Benetnash before Dubhe is about 26 °, the angular distance between the thumb and forefinger of the outstretched hand of an adult is 16-18 °, so the Big Dipper against the background of the outstretched hand will look approximately as shown in Fig. five.

Rice. five Estimating the angular size of the Big Dipper using an outstretched hand.

2. What to do if you wait too long for the desired April? In this case, you need to prepare a compass and use the table proposed here:

Table A
The apparent location of the Big Dipper at the latitude of Moscow at 23:00 local time

Month of the year	Direction	Elevation angle	Note
January	Northeast	30° - 50°	The bucket is turned vertically to the horizon
February	northeasteast	40° - 70°	Bucket deployed vertically
March	East	50° - 80°	Bucket deployed almost vertically
April	Zenith	about 90°	Better look facing north
May	West	55° - 90°	Big Dipper Tilt 80 to 60
June	Northwest West	40° - 70°	Big Dipper Tilt 60 to 40
July	Northwest	35° - 60°	Big Dipper Tilt 40 to 20
August	North-northwest	30° - 55°	The bucket is turned almost horizontally
September	North-northwest	20° - 30°	Bucket deployed parallel to the horizon
October	North	20° - 30°	Tilt of the Big Dipper up from 10 to 30
November	North northeast	15° - 40°	Tilt of the Big Dipper up from 30 to 50
December	Northeast	20° - 40°	Big Dipper tilt up from 50 to 80

The note indicates the location of the Big Dipper in relation to the horizon for an observer looking in the direction of this asterism.

After you have learned to find the Big Dipper in the sky, you will have the opportunity to know all the constellations of the Northern part of the sky.
But the first thing to use the opportunities that have opened up is to determine the position of the Polar Star. If you have found the North Star (Alpha Ursa Minor), then you know the exact direction to the north and can determine the cardinal points.
To find the Polar Star, you need to mentally draw a line between the stars of the edge of the Bucket from Merak to Dubhe and continue to the first bright star - this will be the North Star! You can test yourself mentally by building a Small Dipper from it, as if pouring it into the Big Dipper (Fig. 6). Polar Star is the most important navigational star, and Merak And Dubhe, helping to find it, is also called Pointers.

Rice. 6 How to find the North Star? - Very simple! You need to mentally draw a line through Merak And Dubhe.

In such a position as in Figure 5, the Big Dipper and the Big Dipper can be seen in early autumn closer to midnight, if you look at the starry sky turning to the north ... I believe that the picture does not require further explanation (otherwise, write to the forum)

History and mythology of the constellation Ursa Major

Among the many myths and legends attributed to the work of the ancient Greeks, I like the one that is considered the most ancient, and also the most logically harmonious, the essence of this myth is that in infancy Zeus was raised by the goat Amalthea and two bears Big and Small. Once, when Zeus was already an adult, Amalthea rushed to him and said that the bears, his nurses and intercessors of childhood, the hunters were about to drive into an ambush. Zeus barely ripened at the last moment, snatched his benefactors by the tails from the battle and carried them to heaven, while their tails stretched out. That's why sky bears have such long tails.

Claudius Ptolemy in his star catalog tries to follow the tradition and refers to the constellation Ursa Major the stars that create the image of the bear in the representations of his time. Subsequently, Jan Hevelius, in his atlas "Uranography", tries to follow the descriptions of Ptolemy as closely as possible, unfortunately the original atlas was created in the projection of the "divine gaze" - as if you are looking at the celestial sphere from the outside. In order for the picture to correspond to the "earthly" appearance of the constellation Ursa Major, as well as to highlight the stars, the collage brought to your attention was created:

Rice. 7. The constellation Ursa Major is a collage based on a drawing in the atlas of Jan Hevelius (only those stars that were included in the atlas by Hevelius himself are highlighted). When you hover over the figure, one of the traditional constellation schemes is displayed

Notes:
1. Bayer signs (ε Leo), as well as Flamsteed numbering (54 Leo) and Draper catalog (HD 94402) are used to designate stars.
2. Remarkable stars include even those that are not visible without the help of optics, but in which planets or other features have been found.
