Exploring our solar system

The Solar System

Solar systems consist of:

  • a star
  • planets and dwarf planets in orbit around the star
  • satellites (moons) in orbit around most of the planets
  • comets and asteroids in orbit around the Sun.

The star in our solar system is the Sun. Eight planets orbit the Sun, including the Earth, and smaller dwarf planets such as Pluto, Ceres and Eris.
