Which constellation does Polaris belong to?

Polaris belongs to the brightest star in Ursa minor, also known as Alpha in Ursa 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.

Hope to adopt. Thank you.
