In this galaxy with hundreds of billions of stars, the Milky Way, a star on the inner edge of the galaxy, is called “the sun”. It is a common “yellow dwarf” in the galaxy. This kind of star has a life span of about 10 billion years. After burning fuel, it will eventually evolve into a white dwarf under the influence of its own gravity. The sun has burned for about 4.6 billion years and is currently in the middle of life, warm and stable.
A more detailed observation of the sun reveals that under its gravitational force, the celestial system formed around it hides mystery. There are eight major planets orbiting the sun. The inner four planets, mainly composed of metal and rock, are called “earth-like planets”. The surface of the third-blue azure planet is mainly covered by liquid water. It is wrapped in a dense atmosphere; the fourth planet looks different from the previous one – its surface is covered by red dust, only some white dry ice in the polar regions, the atmosphere is sparse, but And because of the seasonal changes, there will be a violent flow, and dust storms all over the world will occur.
