Sun introduction
The sun is a star in the center of the solar system and the center of the star system where the earth is located. As far as we know, it is one of the most important celestial bodies in the universe. The diameter of the sun is about 1.39 thousand kilometers, which is about 109 times the diameter of the earth. Its mass is about 333,000 times that of the Earth, accounting for 99.86% of the entire solar system. The surface temperature of the sun is about 5500 degrees Celsius, while the core temperature is as high as about 15000000 degrees Celsius.
The sun is mainly composed of hydrogen and helium, and these gases generate huge energy through nuclear fusion reaction inside the sun. In the process of nuclear fusion, hydrogen nuclei fuse into helium nuclei, releasing huge energy and optical radiation, forming the light and heat of the sun. This process is also the reason why the sun remains stable and constantly radiates energy.
