Planets

Saturn

Saturn is named after the Roman god of agriculture and is often described as the most beautiful object in the sky. Saturn's famous rings, which are made from billions of particles of rock and ice, are even visible from Earth with a telescope.

Saturn is sixth in line from the sun and the second largest planet in the Solar System. Like Jupiter, Saturn is made almost entirely of gas and its globe is flattened because of its rapid rotation.

Saturn has the most moons of any of the planets, twenty-five or more, and one of these - Titan - is thought to be similar to Earth before life began.

Average distance from the Sun: 1,427,000,000km
(886,700,000miles)

Length of year: 29.5 Earth years

Diameter: 120,536km (74,901miles)

Average temperature: -202°F (-130°C)
