What are so many stars in the sky?
The stars in the sky twinkle;

The stars in the sky are like scattered pearls;

The stars in the sky are like shining gems;

The stars in the sky are like sparkling fireflies;

The stars in the sky are like small grains of sand in the vast desert.

1. A star refers to a celestial body visible to the naked eye in the universe. The energy activity inside the star makes the shape of the star irregular. Stars can be roughly divided into planets, stars, comets, white dwarfs and so on.

2. The brightest planet is Venus, the fastest star runs at a speed of over 2.4 million kilometers per hour, and H 1504+65 is the hottest white dwarf.

The planet itself doesn't shine, what we see is the sunlight it reflects.

Without external force, all objects tend to gather towards the center under the action of universal gravitation. The most concentrated result is a sphere! Although a star is solid on the surface, it is possible to transform it into a sphere, because solids are also deformable and solid particles are movable.

In 2005, American astronomers discovered a star, and its running speed exceeded 2.4 million kilometers per hour. Astronomers speculate that this star runs so fast, probably because about 80 million years ago, a star encountered a supermassive black hole in the center of the Milky Way. However, this high-speed star will eventually fly away from the Milky Way, which is also the first "escape" star discovered by humans.
