  1. The sun, which sits in the center of our solar system, is a medium-size star. As we all know, the sun provides us with light and warmth; however, as the largest body in our solar system, the sun plays an additional important role. With a diameter of 864,949 miles (1,392,000 kilometers), the sun is more than one million times larger than Earth. Because it is bigger than all the other planets in our solar system, too, the sun exerts a greater gravitational pull. It is this pull that keeps all the planets, including Earth, fixed on their orbital paths. Without this pull, the planets would simply float off into space.
