How to tell the correct position of the Big Dipper?

Polaris belongs to Ursa minor, about 400 light years away from the earth. It is a star with stable brightness and position that can be seen in the night sky.

Often called the Big Dipper, it refers to the seven very bright stars in Ursa Major in the northern sky. Seven stars are arranged in the sky like a spoon, so it is also called Beidou. They indicate the direction of the north. The Big Dipper can not only help us judge the direction, but also indicate different seasons: for example, bucket handle will point to the east in spring, to the south in summer, to the west in autumn and to the north in winter.

Not far from the head of the Big Dipper, at the tail of Ursa minor, there is a star whose brightness is very similar to that of the Big Dipper. It hangs high in the northern sky. It is the North Star. Polaris is the most reliable sign that people can tell the direction at night. Every night, the stars will move from east to west (in fact, our earth rotates from west to east), but Polaris will stay where it is. This is because Polaris is located at the northern end of the earth's rotation axis, just above the north pole of the earth.
