outer planet
Quick Summary
The outer planets in our solar system are Jupiter, Saturn, Uranus, and Neptune. These planets are located beyond the asteroid belt, distinguishing them from the inner, terrestrial planets like Earth and Mars.1
The outer planets are also known as Jovian or giant planets due to their large size and low densities. They are primarily composed of hydrogen and helium, unlike the rocky inner planets. These gas giants possess ring systems and numerous moons. For instance, Jupiter and Saturn are predominantly made of hydrogen and helium, while Uranus and Neptune also contain ice and rock in their composition.2
