outer planets

The outer planets are those planets in the Solar System beyond the asteroid belt, and hence refers to the gas giants, which are in order of their distance from the Sun:

• Jupiter is the largest planet in the Solar System. It has four very large satellites.
• Saturn is the second-largest planet, with a large and bright ring system.
• Uranus is the third-largest planet and the least massive of the four outer planets. It is tilted almost onto the plane of its orbit.
• Neptune is smallest of the four outer planets. It has one big retrograde moon and many small ones.
