Here's why:
* Gravity: The sun's immense mass creates a strong gravitational pull, which keeps all the planets, including Earth, in orbit around it.
* Orbit: Earth and the other planets are constantly moving around the sun in a circular path. This motion keeps us from being pulled directly into the sun.
So, the sun isn't going anywhere. It's been there for billions of years and will continue to be our source of light and warmth for billions more!
