The starry night sky is simple and beautiful.

Formation of the starry sky: The starry sky is formed by celestial bodies visible to the naked eye in the universe.

2. The main constellations of the starry sky in spring are: Lion, Scorpio, Sagittarius and Big Dipper.

3. The main constellations in the autumn night sky are: Wang Xian, Hou Xian, Fairy, Andromeda, Pegasus and Orca.

The main constellations in the winter night sky are Sirius, Taurus, Gemini and Cancer.

The shape of the main elements in the starry sky:

Without external force, all objects tend to gather toward the center under the action of gravity. The most concentrated result is a sphere. Although the surface of a star is solid, solid particles can move because solids can also be deformed, which makes it possible for them to be transformed into spheres.

The energy activity inside the star makes the shape of the star irregular. However, the rocks on the mountain were attracted by the stars and rolled down from a height. Rivers carry sediments from high places to low-lying oceans (rivers are also attracted by stars). These are all examples of concentration. They all change stars from irregular to spherical.
