Judging the season according to the direction of the big dipper.

Judging the seasons according to the direction of the Big Dipper: When the bucket handle of the Big Dipper points to the east, south, west and north, it corresponds to the four festivals of spring, autumn and winter in the northern hemisphere. That is, bucket handle refers to the East, the world is spring, and bucket handle leads the world to summer. Bucket handle refers to the west, and the world is autumn. The barrel handle refers to the north, and it is winter all over the world.

In places with good observation conditions, there are more than 2,000 stars visible to the naked eye in the night sky. On the whole earth, there are more than 7,000 stars visible to the naked eye, including the Big Dipper in the northern sky.

Among these stars, water, gold, fire, wood and earth are planets in the solar system, and they revolve around the sun like the earth. As the only known star in the solar system, the mass of the sun accounts for 99.86% of the total mass of the solar system, and its strong gravity binds the movements of the major planets.

Except for the five planets, the stars in the night sky are actually stars, and the Big Dipper is also a star. Since it is a star, it can emit light and heat through nuclear fusion. Not only that, most stars, like the sun, are surrounded by planets.
