Saturn is the sixth planet from the Sun, with the largest planetary rings in the Solar System. It is the second-largest planet after Jupiter, and recently, with many other moons being discovered, it surpassed the number of Jupiter’s moons and is now considered the planet with the most numerous satellites.

Saturn formed together with the rest of the solar system about 4.5 billion years ago. Gravity pulled swirling gas and dust together and thus the gas giant was created. About 4 billion years ago, Saturn settled into its current position in the outer solar system. Like Jupiter, Saturn is mostly made of hydrogen and helium, the same two main components that make up the Sun.

Saturn has the second-shortest day in the solar system, completing a rotation quite quickly, in about 10.6 hours. However, its orbit around the Sun is slow, completing one trip around the Sun or a year, in about 29.5 Earth years. Its average orbital speed is about 9.68 km/s - 6.01 mi/s.
