The Sun is located in a spiral arm of the Milky Way galaxy. The Sun is the center of Earth’s solar system and makes up 99.8 percent of the mass of the entire solar system.
The Sun is orbited by eight planets, at least five dwarf planets, tens of thousands of asteroids and hundreds of thousands to 3 trillion comets and icy bodies. Since the Sun is a star that does not have a solid body, different parts of the Sun rotate at different rates. At the equator, the Sun completes one rotation approximately every 25 Earth days. At the poles, the Sun completes a rotation once every 36 Earth days.
