Solar System: Some Important Facts

The Solar System is the Sun and all the objects in orbit around it. The formation and evolution of the Solar System began 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. The Sun is orbited by planets, asteroids, comets and other things. Six of the planets and three of the dwarf planets are orbited by moons.

The planets are the biggest objects that go around Sun. Most of the planets have moons that orbit around them just as the planet orbit the Sun. There are at least 173 of these moons in the solar system.

Pluto had been called a planet since it was discovered in 1930, but in 2006 astronomers meeting at the International Astronomical Union decided on the definition of a planet, and Pluto did not fit. Instead they defined a new category of dwarf planet, into which Pluto did fit, along with some others. These small planets are sometimes called plutinos.
