OUTER PLANETS

The outer planets are composed mainly on the 4 gas giants of Jupiter, Saturn, Uranus, and Neptune. Pluto, although considered a terrestrial planet is part of the outer planets, being the most remote. Except for Pluto, these gas giants all rotate on their axis within hours! They also have rings and many moons.

There as been speculation that there is a tenth planet. Theoretically it is possible, but to find such an object is still underway and very difficult. You never know what they will find!
