The Sun and Inner Planets

Our Star — The Sun

The sun is at the center of our solar system! It is a STAR — a giant ball of super-hot gas. The surface temperature is about 10,000°F and the core is 27 million degrees! The sun is so big that 1.3 million Earths could fit inside it. Its gravity holds all the planets in orbit, like a giant invisible leash. The sun provides the light and heat that makes life possible on Earth. Without the sun, Earth would be a dark, frozen rock!
