It is composed mainly of hydrogen and helium and is surrounded by a layer of ammonia clouds. Jupiter is the largest planet in our Solar System, and its immense gravity field is the source of its powerful magnetic field. It is composed mainly of hydrogen and helium, with small amounts of methane and water. Its atmosphere consists of clouds of ammonia and sulfur-containing compounds. Uranus is the seventh planet from the Sun and is its farthest known planet. It is composed primarily of methane and rock and has an atmosphere of hydrogen and helium with some water vapor and carbon dioxide. Its ring system is made up of nine faint rings composed of dust particles and icy satellites.
