Are you talking about the solar system? The solar system starts out as just a pile of interstellar dust, which will freely combine and gather together to form celestial bodies, until all the dust makes up the celestial solar system. When our sun was formed in the solar system, it absorbed enough material to form the sun because of its gravitational force, and other planets, such as Jupiter, would have become the sun, but the gravitational force was not as large as the sun, and the solar system had formed before it absorbed enough material, so it was just a planet.

Most galaxies in the universe are double stars or three-star stars, and our solar system is relatively special, but it is not the only one. Just as most animals on Earth have multiple births, humans generally have one child. So how many should there be, it has to do with the breeding environment.

Cognitive problems. The position of the sun is close enough to the earth, and the life of the earth is ** the sun, so people call this celestial body "sun".
In fact, you can also call Vega the Sun. But no one accepted it, hehe

The Sun is just a very ordinary planet, and there are many sun-like stars in the universe.

Originally, there were 10 suns, and the other nine were shot out by Hou Yi.

That's why you're asking this kind of question"Mythology"Classification of categories would otherwise be mistaken for anti-science.

Why is there only one Earth? Only one of you? Whatever is important is unique.
-
Why do you only have one real dad? While there are countless dads in the world, you only have one. Although there are countless sun-like stars in the sky, there is only one sun on the earth.
-
Because when there is only one sun in the sky, the distance between the earth and the sun is suitable for human survival. That is to say, because there is only one sun in the sky, there are people, and there is what we are discussing today.
Some science fiction** mentions the existence of double stars and triple galaxies, but in those galaxies, no signs of the existence of advanced intelligent beings have been found.
It is now generally accepted that the three galaxies are more likely to have higher intelligent beings than the binary galaxies (binary stars are two suns in the galaxy, and the three-star analogy).
If you have any details, please feel free to ask.
The sun is a star, and most stars are also stars, which are also "suns". The sun is the closest star to us, so we see a big sun, in fact, there are stars during the day, but the sun's light is too strong, and the light of the other stars is obscured, so we can't see it. The stars can be seen as the sun that is far, far away from us, and because it is far away, it looks small and faint. >>>More
That's when the sun catches up with the moon, or the moon is lazy.
