Which constellation does Polaris, which is often used to tell the direction, belong to?
About 15000 to 13000 years ago, Polaris was named Vega because of Yan Zi Shi's Weaver Girl, which originated from the natural worship of ancient stars by ancient Han people. Therefore, it is named Polaris.
The expanded data is different from the western astronomical system centered on ecliptic coordinates. In ancient China, an astronomical system centered on equatorial coordinates was developed. In this system, Polaris is located in the north of the celestial sphere, which undoubtedly has a unique position. In ancient China, it was often used as a symbol of the emperor.
But Alpha Bear has not been the North Star since ancient times. Because the earth's rotation axis swings slowly periodically. Therefore, the position of the sky indicated by the north pole of the earth's rotation axis is also changing, and the "throne" of Polaris may also take turns to sit in the village.
