Constellation _ What is a constellation?

Question 1: Which constellation does the Big Dipper belong to? 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".

Hello. I hope my answer is helpful to you! Thank you for your adoption! ! !

Question 2: Which constellation of the Big Dipper consists of seven stars, namely Shu Tian, Tian Xuan, Tianqi, Tianquan, Yuheng, Kaiyang and Yaoguang. The ancients connected these seven stars and imagined them in the shape of an ancient bucket. 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 bucket handle, which is called Piao in ancient times and easy to identify, hence the name. 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 Big Dipper belongs to Ursa major.

The constellation Ursa major is located in the middle and high latitudes of the northern hemisphere, and it can be seen all year round. The Big Dipper is a part of Ursa Major, located at the back and tail of Ursa Major. 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."

Question 3: 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.

Question 4: What constellation is next to the Big Dipper? The Big Dipper belongs to Ursa major. The nearby constellations that can be distinguished by naked eyes are Leo, Capricorn, Gemini and Northern Corona.

Question 5: Where is the Big Dipper? The Big Dipper consists of seven stars and is a part of Ursa Major in modern astronomy. In fact, these seven stars are relatively easy to identify in the northern sky. The four stars in the hat are near the North Pole, and the three stars in the bucket handle are outside. Most people find the Big Dipper first and then the North Star without tools. The stars in the northern hemisphere rotate clockwise around the north pole of the celestial sphere, so when observing the Big Dipper at different times, its position will be different. Do you remember an old saying in China: 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; The barrel handle refers to the north, and it is winter all over the world. In other words, in the evening of spring, you can see that the handle of the bucket points to the east, and so on. At this time, you can find the bucket spoon along the direction of bucket handle. If the latitude is high enough, you can also see it all night (of course, the Big Dipper may be overhead for a while).

Question 6: What constellation is the Big Dipper located in? In the northern hemisphere, there is a famous constellation Ursa Major, which is composed of seven bright stars, commonly known as Seven Spoons. They are called Shu Tian, Tianwangxuan, Tianjing, Tian Quan, 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 at 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.

Question 7: What constellation is next to the Big Dipper? In ancient China, the seven bright stars in Ursa Major were considered to be 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.

Question 8: What is the relationship between the Big Dipper and the constellation? As the Big Dipper said upstairs, I will 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 irregularly intersect with the 12 constellation. For example, A star in Scorpio is Antares, and A star in Taurus is Bisuwu. The ancient people in China divided the stars in the sky into 28 groups, covering the northern and southern celestial spheres, and the 12 constellation. As the name implies, it is the twelve constellations near the ecliptic. 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. In short, this is it.
