What is the name of each position in the Big Dipper?

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

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, they were called Shu Tian, Tian Xuan, Tianji, Tianquan, Yuheng, Kaiyang and Yaoguang respectively. A straight line from Tian Xuan runs through Shu Tian, which is about five times as long as it. You can see a star as bright as the Big Dipper, which is the North 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.

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 ancient Arabs 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.

I don't know. It should be the same in Japan, right? !
