What constellation is Polaris?

Ursa minor, the star closest to the north celestial pole.

Polaris, also known as Beichen, Zigong and Ziweiyuan, refers to the star closest to the North Celestial Pole, and now it generally refers to Gou Chenyi.

Polaris is located at the northern end of the earth's axis, which is five times as long as the extension line connecting Tian Xuan and Shu Tian in the Big Dipper. Because the earth rotates, and Polaris happens to be on the axis of celestial rotation, it is still relative to other stars. Polaris is about 434 light years away from the earth and has a diameter of about 52 million kilometers.

Gou Chenyi is actually composed of three celestial bodies: Polaris Aa, Polaris B and Polaris Ab. It was once named Vega, and its name came from the story of _ Zishi (matriarchal clan tribal leader) weaving linen clothes in the late Paleolithic period, but now it is called the North Star because it is closest to the North Pole. The main star Polaris A is a huge, bright and ancient yellow Supergiant star. Polaris A is six times the mass of the sun, and if it is placed with the sun, its brightness is 2000 times that of the sun.
