What is the nickname of Polaris?

Polaris is also known as Purple Palace and Purple Weiyuan.

According to legend, the discoverer of Polaris was Yan Zi Shi, a coward. Polaris refers to the star closest to the north celestial pole, so Polaris is not always the same. At present, it refers to Gou Chenyi. About 434 light years away from the earth, it is a star with stable brightness and position that can be seen in the night sky.

Polaris is a bright star in the northern part of the sky, very close to the north celestial pole, almost opposite the earth axis.

Polaris is a very important indicator of field activities and ancient navigation direction, ranging from stargazing to astrophotography. The accurate positioning of the equatorial observatory in the observation room is also a very important constellation to identify the direction. Because Polaris is closest to true north, people on earth have been navigating by its starlight for thousands of years.

Extended data star finding method

1. You can find the Big Dipper first, and then find the North Star through 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. Of these seven stars, six are secondary stars and one is tertiary. Through the connection of two stars (Shu Tian and Tian Xuan) in Doukou, Polaris was discovered after extending in the direction of Doukou for about five times.

2. The intersection of Tianjing and Tianquan of Douxing and Kaiyang and Yaoguang is connected with Yuheng, extending seven times, and Polaris can also be found. The intersection of the left and right sides of the W-shaped Cassiopeia is five times longer than the middle star, which is also the position of the North Pole star.
