Learn about the Outer Planets Reading

The outer planets—Jupiter, Saturn, Uranus, and Neptune—are massive worlds made mostly of gas and ice. Known as the gas and ice giants, they are located far from the Sun, where the cold allowed gases like hydrogen and helium to form these colossal planets. Jupiter, the largest, has the Great Red Spot, a centuries-old storm. Saturn is famed for its dazzling rings. Uranus rotates on its side, while Neptune boasts supersonic winds. These planets have numerous moons, some with fascinating features like Europa's ocean and Titan's methane lakes. Unlike the rocky inner planets, the outer planets lack solid surfaces, emphasizing the diversity of our solar system.
