What is the Big Dipper?

Question 1: What does the Big Dipper mean? The Big Dipper, also known as the Big Dipper, Polaris and Kuixing, belongs to Ursa Major. It means that there are seven bright stars in the northern sky, namely Shu Tian, Tian Xuan, Tianji, Tianquan, Yuheng, Kaiyang and Yaoguang. We often call them the Big Dipper.

China has written many works describing the Big Dipper in past dynasties, such as The Passage of Shi Gan, Yu Shu, Historical Records, Huainanzi and The Book of Jin. Another car brand "Big Dipper".

1 overview of astronomy

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

2 Name source

The Big Dipper is made up of seven bright stars. It looks like a bucket spoon and is easy to identify, hence its name. The first two stars of its spoon are called "pointing to Polaris", pointing to Polaris, which can help us identify the direction at night.

2. 1 the movement of Beidou

The Big Dipper revolves around the North Star once a year. "My Tube" and "Huainanzi": "bucket handle refers to the east, and the world is spring. Bucket handle's Guide, It's Summer in the World. Bucket handle refers to the west, and the world is autumn. Bucket handle refers to the north, and it is winter in the world. " Refers to the method of observing the direction of bucket handle at dusk to determine the season, which is called annual apparent motion; Because of the earth's rotation, the Big Dipper is also doing circular motion around the north celestial pole every day, which is called Sunday apparent motion. This is why the ancients observed the direction of bucket handle at dusk every day to determine the time. With the change of seasons, the bucket handle of the Big Dipper moves clockwise.

2.2 Composition of Beidou

The Big Dipper consists of seven stars. 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 bucket handle, which was called Piao in ancient times. 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 to find the North Star. These two stars are also called "finger stars".

Question 2: What does the Big Dipper mean? The Big Dipper is the seven stars near the North Star. It consists of Shu Tian, Tian Xuan, Tianji, Tianquan, Yuheng, Kaiyang and Yaoguang, so the ancients called it the Big Dipper. 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". The ancients connected these seven stars with dotted lines, and Shu Tian, Tian Xuan, Tian Ji and Tian Quan formed a fighting body, which was called the champion. Yuheng, Kaiyang and Yaoguang make up bucket handle, which is called gourd ladle. The whole thing forms a bucket with a handle. Because living in the north, it is called Beidou. Taoism attaches great importance to Beidou, and worships it for two reasons: on the one hand, when traveling in Elysium, Taoist can use Beidou to determine the direction and distinguish the alternation of seasons. The Big Dipper is close to the North Star, which connects Shu Tian and Tian Xuan in a straight line. When the distance is extended by five times, you can find the North Star, which is a symbol of the north. At the same time, people can also decide the season according to the direction of bucket handle at the beginning of fainting: bucket handle refers to the east, and the world is spring; Guide to barrel handle, it's summer in the world; 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. On the other hand, the deeper reason is that, in the eyes of Taoist people, the big dipper star is closely related to life and death. "Beidou lives in the sky, which is the hub of the sky, and it swims at four o'clock. Everything from heaven, earth, day, month, five stars, obsidian, six feet and twenty-eight nights, all the immortals are true, from the emperor down to Li Shu, Shoulu, rich and poor, life and death, all ghosts and gods belong to President Beidou. If a person sincerely hopes, he will answer. "

Question 3: What does the Big Dipper stand for? The Big Dipper is: one Shu Tian, two Tian Xuan, three celestial poles, four celestial bodies, five Yuheng, six Kaiyang and seven Yaoguang. The ancients thought that Beidou had its own meaning, and the Book of Jin&; ; #8226; Tian said that the Big Dipper is located in the north of Qiu, its pivot is the sky, its grace is the earth, its force is the time, its balance is the sound, the sun is the law, and Ursa major is the star.

Taoism calls the Big Dipper the Seven-Yuan Xie Hexing King, who lives in the Seven Palaces of the Big Dipper, namely: Shu Tiangong Wolf-greedy Star King, Tian Xuan Palace Giant Gate Star King, Tianjigong Lucun Star King, Tianquan Palace Wenqu Star King, Yuheng Palace Lian Zhen Star King, Kaiyang Palace Wuqu Star King and Yaoguang Palace Broken Army Star King.

Taoism calls the Big Dipper the Seven-Yuan Xie Hexing King, who lives in the Seven Palaces of the Big Dipper, namely: Shu Tiangong Wolf-greedy Star King, Tian Xuan Palace Giant Gate Star King, Tianjigong Lucun Star King, Tianquan Palace Wenqu Star King, Yuheng Palace Lian Zhen Star King, Kaiyang Palace Wuqu Star King and Yaoguang Palace Broken Army Star King.

Shu Tian's return.

General: The Book of the Heavenly Palace Historical Records even says: Beidou is the image of the emperor's car, Shu Tian, Tian Xuan, Tianji, Tianquan, Yuheng, Kaiyang and Yaoguang have their own attributes, and Shu Tian is the seven-star hub; The sky turns around; Tianqi leads the change; Balance of heaven and power; Yuheng is the balance of weight; Kaiyang is Kaiyang; Shake the lamp means shake the lamp.

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".

The significance of the Big Dipper to our monasticism is well known. I think it is good for us to know more about the Big Dipper. I don't know which plate to send. If Bambusa is more suitable, move it.

With the help of modern astronomical means, we know that Polaris is actually composed of three stars, and its position is constantly changing. In the future, other stars will become new "North Pole" stars. In addition, Shu Tian (Beidou-1) is actually a binary star, while Kaiyang (Beidou-6) is actually a four-star.

I think this should not be accidental, but meaningful. It's a pity that my knowledge is shallow and I can't understand the mysterious and subtle avenue contained in it.

The following is a detailed introduction.

Polaris is the alpha star of Ursa minor, and China's name is Dog Chen Yi or Beichen. Polaris is about 400 light years away from us. It is the bright star closest to the North Celestial Pole at present, and the distance is less than1; So for the observers on the earth, it seems that it does not participate in Sunday sports, and it is always located at the north celestial pole, so it is called the North Star. It is this feature that makes it one of the most important stars in the whole day.

Polaris is a triad of three stars. The main star A is the nearest Cepheid variable with an apparent magnitude of 2. 02, the period is 3. No.7 is a yellow Supergiant star with a spectral classification of F8Ib. The main star A is a single-spectrum binary star with an orbital period of about 30 years. Companion b visual magnitude 8. 6. The distance to the main star is 18 ".

Due to precession, the celestial pole moves around the yellow pole with a period of about 26,000 years. During this period, some bright stars near the north celestial pole were awarded the title of Polaris in turn. Around 2750 BC, Alfa Draco (Chinese name right pivot) was once the North Star. It's only been nearly a thousand years since Ursa minor became the North Star. 1000, 6 degrees from the north celestial pole; . Since 1940, the distance between α Ursa minor and the north celestial pole has been less than1; And move to the north celestial pole at a speed of about15 "per year. At about 2 100, the angular distance between them will be minimized, only about 28'. After that, alpha Ursa minor will gradually move away from the north celestial pole. In 4000 AD, Alpha Cepheus will become the Polaris. The Polaris in 7000 AD, 10000 AD and 14000 AD will be Alpha Cepheus (named Tiangou V in the middle), Alpha Cygnus (named Tianjin IV in the middle) and Alpha Lyra (named in the middle).

The Big Dipper

The seven bright stars of Ursa major are arranged in a barrel. The names of the seven stars in China are Shu Tian (Beidou No.1), Tian Xuan (Beidou No.2), Tianji (Beidou No.3), Tianquan (Beidou No.4), Yuheng (Beidou No.5), Kaiyang (Beidou No.6) and Yaoguang (Beidou No.7). The first four stars in the Big Dipper, namely, Shu Tian, Tian Xuan, Celestial Pole and Tianquan, form a barrel shape, hence the name Dou Kui, or Kuixing, also known as Xuan Ji. Yuheng, Kaiyang and Yaoguang form bucket handle (Dou) or Yuheng. Among the Big Dipper, all six stars are second-class except Tianquan, which is a third-class star. The Big Dipper is not far from the north celestial pole, so it is very easy to identify. They often ... >>

Question 5: What does the Big Dipper mean? The Big Dipper consists of seven stars, also called the Big Dipper, which is located in the north direction and looks like an ancient rice container.

Question 6: What does the Big Dipper look like? The Big Dipper is a part of Ursa major. Graphically, the Big Dipper is 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." Beginners can look for other constellations in turn from the Big Dipper.

The Big Dipper is named α, β, γ, δ, ε, ζ and η respectively from the upper end of the bucket to the end of bucket handle. In ancient China, it was twitching.

They are Shu Tian, Tian Xuan, Tianji, Tian Quan, Yuheng, Kaiyang and Yaoguang. From "Tian Xuan" to "Shu Tian", a straight line extends outward, about.

More than five times longer, you can see a star that is almost as bright as the Big Dipper, that is, the North Star. Taoism calls the Big Dipper King Xie Hexing, who lives in the north.

The seven palaces are: Shu Tiangong Wolf-Hungry Star Jun, Tian Xuan Palace Giant Gate Star Jun, Tianjigong Lucun Star Jun, Tianquan Palace Wenqu Star Jun, Yuheng Palace Lian Zhen Star Jun, Kaiyang Palace Wu Qu Star Jun and Yaoguang Palace Broken Army Star Jun.

Some Taoist books also say that according to the time of birth, a person's life is divided into seven star kings: "greedy wolves are too star kings, and children are born;" The giant gate is a distant king, and the ugly returnee is a stranger; Road inch is a real star, and strangers belong to it; Wenqu Xinxing Jun, born by strangers; Lian Zhen Port promotes the army, and Shengsheng Chen belongs to it; Wu Quji is no stranger and belongs to Wu Shengren. " Everyone can find their own star according to their birthday.

Shu Tian, Tian Xuan, Tianji and Tian Quan are the four stars that make up the Big Dipper, and the three stars in the shape of handles make up Yuheng, Kaiyang and Ursa Major respectively.

Bright and dark binary stars. The star in the center of the handle is called "Kaiyang", and there is a fourth-class companion star named "Fu" at the distance of 1 1. Kaiyang and the auxiliary star form a binary star, which can be recognized by the naked eye. Kaiyang itself is also a binary star.

The position of the Big Dipper in the sky is different in different seasons. Therefore, the ancients in China determined the seasons according to their position changes: "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 it is winter all over the world. "

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.
