Is the Big Dipper in the north of the sky? Seek authority.

Relative to Polaris, the position of the Big Dipper is basically unchanged, but the rotation of the earth will make people think that the Big Dipper revolves around Polaris (actually around the earth axis). If you keep watching the Big Dipper at night, you will find that it also rotates from east to west, and you can't see it when the sun comes out during the day. When the earth revolves to other places, such as half an orbit, the night is exactly the other half of the space seen at night six months ago, so seeing the direction of the Big Dipper is equivalent to seeing the shape of the Big Dipper during the day six months ago. 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".
