What constellation does Polaris belong to?

Polaris belongs to Ursa minor.

It is about 430 light years away from the earth and its mass is about four times that of the sun. It is a star with stable brightness and position that can be seen in the night sky. Because Polaris is closest to true north, people on earth have relied on its starlight to navigate for thousands of years.

Polaris is the brightest star in Ursa minor, which is also a star in Ursa major. It is a yellow giant star with spectral type F. Like Ursa Major, the tail of Ursa Major can also be regarded as the handle of a bucket (or spoon), so it is called "Little Beidou".

Ways to find Polaris:

Polaris is a bright star in the northern part of the sky, very close to the north celestial pole, almost facing the earth axis. Seen from the northern hemisphere of the earth, its position is almost unchanged, so it can be used to identify the direction.

Because of the rotation of the earth, Polaris is just on the axis of celestial rotation, so it is relative to other stars. However, the Polaris is not completely at the center of the north celestial pole. In fact, it is circling at a very slow speed, and looks unchanged compared with other stars.
