Glossary term: Saturn
Description: Saturn is known as the jewel of the Solar System. It can be seen with the naked eye as a matte point of light in the sky, even though it is over a billion kilometres away from Earth; the beautiful rings that surround it can be seen with a telescope. It is the sixth planet from the Sun, and the second largest of the planets in terms of size and mass, with a diameter of 120,000 km and with the lowest density of the Solar System planets, less dense than water on Earth. Saturn revolves around the Sun in an elliptical path; it takes 29 Earth years to complete one revolution around the Sun and nearly 11 hours to complete one rotation around its own axis. It is one of the gas giants, with 82 known moons, of which 53 have been officially named. Among these moons, Titan is the largest, and is the only moon in the Solar System with a significant atmosphere.Related Terms:
