AMY’S™ ASTRONOMY WORKSHOP
Our Solar System
Our Solar System began about 4.5 billion years ago, when the Sun was born. The system consists of the Sun, the nine planets, their moons, and other asteroids, comets, and meteors. The Earth is about 93 million miles from the Sun, and Pluto, the most distant planet, is about 3.6 billion miles from the Earth. As you can tell, our Solar System is a very big place!
