Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius about nine times that of Earth. It is best known for its prominent ring system, which is composed mainly of ice particles with a smaller amount of rocky debris and dust. Saturn is named after the Roman god of wealth and agriculture, which is equated to the Greek Cronus, the Titan father of Zeus. In Hebrew, Saturn is called Shabtai (שבתאי), named after the biblical figure Shabtai. In Arabic, it is known as Zuhal (زحل), and in Hindi, it is called Shani (शनि). Saturn's interior is probably composed of a core of iron, nickel, and rock, surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and helium, and an outer gaseous layer. The planet exhibits a pale yellow hue due to ammonia crystals in its upper atmosphere. Saturn has 146 known moons, with Titan being the largest and the only one with a substantial atmosphere. The planet's ring system is divided into several distinct components, with the most prominent being the A, B, and C rings. Saturn's magnetic field is about 578 times less powerful than Jupiter's, and its magnetosphere is the second largest of any planet in the Solar System, although it is still much smaller than Jupiter's.
