Giant planets

Jupiter, Saturn, Uranus and Neptune, the four planets farthest from the Sun, are giants made mostly of gas, with no solid ground. Jupiter is the biggest, about 11 times as wide as the Earth; Saturn has bright rings of ice and rock; Uranus is tipped on its side; Neptune is the farthest. All four have rings and many moons.
