The words solar system refer to the sun and all of the objects that travel around it -- planets, natural satellites such as the moon, asteroid belt, comets, and meteoroids. Our solar system is part of a spiral galaxy known as the Milky Way.

Age: 4.6 Billion Years

Surface Temperature: 5500 °C

The sun is a star, a hot ball of glowing gases at the heart of our solar system. Without the sun's intense energy and heat, there would be no life on Earth. And though it is special to us, there are billions of stars like our sun scattered across the Milky Way galaxy.

Volume: 1.3 million Earths

The sun is the center of our solar system. It contains almost all of the mass in our solar system and exerts a tremendous gravitational pull on planets and other bodies.

We measure distances in our solar system by Astronomical Units (AU). One AU is equal to the distance between the sun and the Earth, which is about 150 million km (93 million miles).
