Saturn

Saturn is the sixth planet from the Sun and is known for its distinctive rings that are made up of millions of individual particles of ice and rock. It has a diameter of about 116,460 kilometers and a day on Saturn is similar to Jupiter's, lasting about 10 hours and 42 minutes, while one year is equal to about 29 Earth years. Saturn has a thick atmosphere mostly composed of hydrogen and helium, with small amounts of methane and other gases. The planet also has many moons, with the largest being Titan, which is the only moon in the solar system known to have a dense atmosphere. Saturn has been explored by spacecraft such as the Cassini-Huygens mission, which provided valuable information about the planet's rings, atmosphere, and moons.
