There are seven bright stars in the northern sky arranged in a barrel shape. We often call them the Big Dipper.

The names of these seven bright stars are: Shu Tian, Tian Xuan, Tianji, Tian Quan, Yuheng, Kaiyang and Yaoguang. The first four stars are called "Dou Kui" or "Xuan Ji"; The last three stars are called "bucket" and "bucket handle". These seven stars are α, β, γ, δ, ε, ζ, η in Ursa major, and the other six stars are all second-class except the celestial force δ. The line connecting Tian Xuan β and Shu Tian α is about five times longer, and Polaris can be found. Therefore, beta and alpha stars are also called "Polaris".

What constellation does the Big Dipper belong to? What constellation does Polaris belong to?

The Big Dipper belongs to Ursa major, and Polaris belongs to the brightest star in Ursa minor, also known as Alpha minor.

China called it "Gouchenyi" or "Beichen" in ancient times. On the constellation diagram, it is on the tip of the bear's tail.

Draw a straight line from the two stars β and α at the mouth of Ursa major and extend to the other side five times away from them. There is a star that is not very bright. It is the alpha star of Ursa minor and the famous Polaris. Throughout the year, no matter where the handle of Beidou points, the connection between β and α always extends to Polaris. Therefore, these two stars were also called Polaris in ancient China. Connecting the main bright stars in the constellation is more like a little Beidou than a little bear. The Big Dipper in Ursa minor is not only much smaller than that in Ursa major, but also the other seven stars are smaller than 4 except that α and β are second-class stars and γ is third-class. Unlike the Big Dipper in Ursa Major, the other six stars are all second-class except δ. So this little Big Dipper is far less eye-catching than the Big Dipper. People usually notice only the North Star.

What constellation is the Big Dipper located in?

There is a famous constellation Ursa major in the northern hemisphere, which consists of seven bright stars, commonly known as seven spoonfuls of stars, which are called Shu Tian, Tianwangxuan, Apocalypse, Tianquan, Yuheng, Kaiyang and Yaoguang respectively. This is the famous "Big Dipper". Yuheng is the brightest in the Big Dipper, and Tian Quan is the darkest. The Big Dipper was a symbol of judging seasons in ancient times. In ancient books, "bucket handle refers to the east, and the world is spring; Bucket handle guide, the world is summer; Bucket handle refers to the west, and the world is autumn; Bucket handle refers to the north, and the world is winter. ". Find the eye-catching Big Dipper, connect the two stars on the outer edge of the Dipper's mouth into a line, and extend it to the mouth of the mouth for five times, then you can find the Polaris that can tell the direction. Polaris is just an ordinary second-class star, 400 light years away from the earth where we live. The earth's axis of rotation always points to Polaris, so people in the northern hemisphere can tell the direction through it no matter what season.

What constellation does the Big Dipper belong to?

According to the modern international star naming system, the Big Dipper belongs to Ursa major.

The Big Dipper consists of seven stars, namely Shu Tian, Tian Xuan, Tianji, Tianquan, Yuheng, Kaiyang and Yaoguang. Ancestors connected these seven stars and imagined them as barrels of wine in ancient times. Shu Tian, Tian Xuan, Tian Ji and Tian Quan form a bucket body, Gu Yuekui and Dou Kui; Yuheng, Kaiyang and Yaoguang are composed of the ancient structure of bucket handle. Tian Xuan and Shu Tian are in a straight line, extending about five times, and then you can find Polaris, which constitutes the Polaris area.

The sequence of the Big Dipper from Doukou to bucket handle is Shu Tian, Tian Xuan, Tianji, Tianquan, Yuheng, Kaiyang and Yaoguang. The top four are called "Dou Kui", and some are called "Xuan Ji"; The latter three are called "bucket handle", and some are called "Yuheng". Modern stars are named Ursa major, Ursa major, Ursa major, Ursa major, Ursa major, Ursa major, Ursa major, Ursa major and Ursa major. Connect the two stars at the mouth of the barrel and extend to the mouth of the barrel for five times, and you can find the North Star. These two stars are also called "finger stars".

What constellation does the Big Dipper belong to?

The Big Dipper is a part of Ursa major. It consists of five bright second-class stars and two third-class stars in the shape of a spoon, just like an ancient vessel for holding wine, hence its name. As for the name Beidou, it is also different from the six stars in Nandou. The six stars in Nandou are also arranged in a barrel shape on Sagittarius, hanging low in the summer night sky. The Big Dipper is equivalent to the waist and tail of Ursa major. Four of them make up the bucket spoon, and the other three make up the bucket handle.

Graphically, the Big Dipper is located on the back and tail of the big bear. Of these seven stars, six are secondary stars and one is tertiary. Through the connection of the two stars in the mouth of the bucket, it extends about 5 times in the direction of the mouth of the bucket and finds the Polaris. "Star Recognition Song" has: "Star recognition begins with Beidou, and then begins from north to west." Beginners can look for other constellations in turn from the Big Dipper.

What constellation is next to the Big Dipper?

In ancient China, the seven bright stars in Ursa Major were considered to be in the shape of a spoon, which is what we often call the Big Dipper. The second star on the spoon handle is Zeta Star, which was called Kaiyang Star in ancient China. If you look carefully, you will find a dark star near it. This dark star is called Ursa Major 80. The ancients saw that it was always close to Kaiyang Star, just like the patron saint of Kaiyang Star, so it was called Fu. Kaiyang star and auxiliary star form a pair of binary stars.

What constellation is the Big Dipper?

The Big Dipper is a part of Ursa major. Graphically, the Big Dipper is located at the tail of Ursa Major.

What is the relationship between the Big Dipper and the constellation?

Well, as the Big Dipper said upstairs, I'll say the latter. The highest day on the earth is a star, and the 28 constellations are just the ancient division method of China. There is no necessary connection, but they will have an irregular intersection with the 12 constellation. For example, a star in Scorpio is Antares, and a star in Taurus is Bisuwu. The ancients in China divided the stars in the sky into 28 groups, covering the northern and southern celestial spheres, and the 12 constellation, as its name implies, is the zodiac. Except for the special Ophiuchus, everything else is on the ecliptic. There are 88 constellations in the whole day, of which 13 is the zodiac constellation. In this 13 constellation, only Ophiuchus is not on the ecliptic, which is simply the case.

The constellation orientation of the Big Dipper.

The Big Dipper is a part of Ursa major. Graphically, the Big Dipper is located at the tail of Ursa Major. Six of these seven stars are secondary stars, and 1 is tertiary. Through the connection of the two stars in the mouth of the bucket, it extends about 5 times in the direction of the mouth of the bucket and finds the Polaris. "Star Recognition Song" has: "Star recognition begins with Beidou, and then begins from north to west." Beginners can look for other constellations in turn from the Big Dipper. The seven stars of Ursa Major are arranged in the shape of a spoon. The ancients attached great importance to Beidou because it can be used to identify the direction and set the season. Shu Tian, Tian Xuan, Tianji and Tian Quan are the four stars that make up the Big Dipper, and the three stars with handles are Yuheng, Kaiyang and Ursa Major. The star in the center of the ladle handle is called Kaiyang, and there is a fourth-order companion star called auxiliary star at the distance of 1 1. Kaiyang and the auxiliary star form an optical binary star, which can be recognized by naked eyes. Kaiyang and auxiliary stars are also the only physical binary stars visible to the naked eye all day. The position of the Big Dipper in the night sky is different in different seasons. Therefore, ancient China people determined the four seasons according to its position change. "Shi Gan Jing Jing": "Beidou is called the Seven Houses, the Minister of the Emperor, and the Emperor Car." The emperor sat on the Big Dipper and inspected the four directions, and it was cold and hot at four o'clock. The ancient book "Guo Guanzi" records: "Dou Dong refers to human spring; Fighting in the south and fighting in the north, the world is summer; Fighting against the west means that the world is autumn; The northern war is the winter in the world. " In ancient times, Polaris was regarded as a symbol of God, and Beidou was the imperial chariot that God drove when he traveled around the world. The year began in spring, when Beidou was in the east, so God began to patrol from the east, so Yi Zhuan: "The Emperor was shocked" and divination was in the east. Among the Big Dipper, "Yuheng" is the brightest, and its brightness is almost close to the first-class star. "Tianquan" is the blackest and is a third-class star. The other five are all second-class stars. There is a small companion star named Fu near Kaiyang, which has always attracted people's attention with its beautiful and clear appearance. It is said that in ancient times, people used it as a "test star" to test soldiers' eyesight when recruiting soldiers. The Big Dipper always moves slowly in the sky. Five of the stars move in one direction at roughly the same speed, while Shu Tianhe and Yao Guang move in the opposite direction. Therefore, in the long cosmic changes, the shape of the Big Dipper will change greatly. After 654.38+ million years, we will not see this handle shape. The Big Dipper is also called "Beidou" for short. Not far from the north celestial pole, seven bright stars are arranged in a barrel shape (see photo). All six stars are second-class except delta, which is a third-class star. Polaris can be found by connecting the first two stars of the Big Dipper and extending it to the mouth of the Big Dipper for about five times, which is usually used as a sign to indicate the direction and identify the constellation. In addition, according to the bucket handle curve of the Big Dipper, after drawing an arc, you will meet arcturus, which is one of the 2 1 bright stars, that is, the alpha star of the constellation Capricorn.
