The planets that orbit the Sun beyond the asteroid belt in our solar system are known as the outer planets.
Besides their location, they share many other similarities, except for Pluto, which is a highly unusual planet.
Jupiter, Saturn, Uranus, and Neptune are all much larger than Earth and are made mostly of gas.
This has earned them the nickname of gas giants.
The outer planets, except for Pluto, are also known as Jovian planets because they resemble the planet Jupiter.
Jove is the Greek name for “Jupiter”.
