Planet Saturn: Facts About Saturn’s Rings, Moons & Size

Saturn is the sixth planet from the sun and the second-largest planet in the solar system. It’s the farthest planet from Earth that’s visible to the naked human eye, but the planet’s most outstanding features — its rings — are better viewed through a telescope. Although the other gas giants in the solar system — Jupiter, Uranus and Neptune —  also have rings, Saturn’s rings are particularly prominent, earning it the nickname the “Ringed Planet.”

Physical characteristics of Saturn

Saturn is a gas giant made up mostly of hydrogen and helium. Saturn’s volume is greater than 760 Earths, and it is the second most massive planet in the solar system, about 95 times Earth’s mass. The Ringed Planet is the least dense of all the planets, and is the only one less dense than water. If there were a bathtub big enough to hold it, Saturn would float.
