What do Saturn, Jupiter, Uranus, and Neptune have in common?

Saturn, Jupiter, Uranus, and Neptune are all classified as Jovian planets, which is a term used to describe the gas giants of our solar system. This classification includes the large planets that are primarily composed of gases such as hydrogen and helium, distinguishing them from terrestrial planets, which are primarily rocky.

The term "Jovian" originates from the largest of these planets, Jupiter, which is often associated with the Roman god Jupiter. Jovian planets are known for their substantial size, thick atmospheres, and significant gravitational fields. They also typically have numerous moons and complex ring systems.

While it is true that these planets have rings and some may refer to them as gas giants, the defining characteristic that they share, which encompasses all four, is their classification as Jovian planets. This highlights their shared formation history and physical properties compared to terrestrial planets like Earth or Mars, which are solid and smaller in size.
