How to use the Big Dipper to find the North Star and draw a picture?

First, please find bucket handle of the Big Dipper, and follow the opposite direction of bucket handle to find the two stars after the fight. Then imagine connecting two stars with a straight line.

Then, extend this imaginary straight line five times-there is a star with medium brightness. In that area with few stars, the star that shines alone is Polaris. The position of the North Star is vertical, and the horizon you see is the north.

Extended data:

Polaris is almost directly above the north axis of the earth. In the past, vagrants in the north of the earth used Polaris to keep their course. Polaris is not as bright as the Big Dipper. It needs a dark environment to see it. Polaris is located in Ursa minor, at the end of the handle of Little Beidou.

In other words, Little Beidou is not a complete constellation, it is only an obvious part of Ursa minor. Polaris is not the brightest star in the sky as most people know, and its brightness can probably rank in the top 50 of the whole day. However, as long as the weather is clear and there is no light pollution, Polaris is bright enough for us to see it.
