Why do stars shine?

The reason why the star shines: the star itself does not shine, but what people see is the sunlight it reflects. Stars are big celestial bodies like the sun. They will react inside themselves and radiate energy into space in the form of light.

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.

The brightness of a star is usually expressed in magnitude. The brighter the star, the smaller the magnitude. 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.

Extended data:

There are about 6,000 stars that can be observed by the naked eye. Of course, this number will vary greatly because of everyone's different eyesight. In addition, the number of stars seen in a place varies with geographical latitude. People in the equatorial region can see all the stars overnight, while people in the northern hemisphere can never observe the starry sky in the southern hemisphere; In the southern hemisphere, the higher the latitude, the fewer stars you see.

A star is a stationary planet in the universe. It doesn't revolve around a planet, but can react by itself, emitting light and heating. Our sun is the most famous star. A planet is a planet that revolves around a star. The nine planets we live in, such as the Earth, Mars and Jupiter, all belong to planets, and the planets themselves do not emit light.

Astronomical observation, you can see them because the planet reflects sunlight; Satellites are planets orbiting planets. The moon in the night sky is a satellite orbiting the earth. Like a planet, a satellite can be seen because it reflects sunlight.

Stars are actually stars, just like the sun, each star will glow and heat itself. The reason why the stars we see are not as bright as the sun is because the stars are far away from the earth. If we get closer, we will find that every star is like a small sun.
