Our Solar System

The solar system consists of the sun and everything that orbits or travels around the sun. This includes the eight planets and their moons, dwarf planets, and countless asteroids, comets, and other small, icy objects. However, even with all these things, most of the solar system is empty space.

The solar system itself is only a small part of a huge system of stars and other objects called the Milky Way galaxy. The solar system orbits around the center of the galaxy about once every 225 million years. The Milky Way galaxy is just one of the billions of galaxies that in turn make up the universe.
