Which galaxy does Polaris belong to? Does the Big Dipper belong to the same galaxy?

It seems a little magical that Polaris is always in the north of the earth. In the galaxy composition of the whole universe, the north direction of Polaris is quite sensitive, which is the uniqueness of Polaris. We can't help asking a question, do Polaris and the whole Big Dipper belong to the same galaxy?

In fact, the Big Dipper does not belong to the same galaxy. Polaris belongs to Ursa minor and is the brightest star in Ursa minor. Its astronomical code is Alpha Ursa minor. Polaris is not far from the earth, only 434 light years away. In the whole Ursa minor, Polaris is located at the tip of the bear's tail, so it is quite representative.

The secret of Polaris doesn't stop there. In fact, it is the legendary three-in-one system, the so-called three-body system. The other two companion stars are inconspicuous. This star in the northern sky of the earth is hard to see now. Because of the influence of human outdoor lighting on the starry sky, Polaris will continue to dim.

In addition to Polaris, Beidou-1, the star code-named Shu Tian, belongs to Alpha Ursa major, the hungry wolf star, which is only 124 light-years away from us, and Beidou-2 is Beta Ursa major, which is about 79 light-years away from the Earth. The Big Dipper belongs to Ursa major, but Polaris belongs to Ursa minor.

Polaris is also farther away from the earth. Except for Alpha Ursa major, the other five stars of Beidou are within 100 light-years from the Earth. I remember the clear night sky when I was a child. The Big Dipper is always the brightest combination in the northern sky. On a clear summer night, watching the bright stars in the sky fall asleep may never be enjoyed by children nowadays. what do you think?
