While Uranus and Neptune, the ice giants, are made up of water, ammonia and methane ices on their mantle, and hydrogen, helium and methane gases on the surface. Saturn: The Cassini spacecraft wrapped up more than a dozen years of observation at Saturn in 2017. Astronomers have also determined that some exoplanets could be ice giants, as well. In its latter months, the mission examined Saturn's gravity and magnetic fields, looked at the rings from a different angle than before, and plunged into the atmosphere deliberately (a move that will reveal more about the structure of the atmosphere.). Its atmosphere consists mostly of hydrogen, helium, ammonia and methane. Gas giants are large planets that contain more than 10 times the mass of Earth, they are also known as the Jovian or Outer Planets. The formation of gas giants has to take place within the lifetime of the gaseous protoplanetary disk surrounding a young star in which the planet is forming.

This material forms a ring (or rings) around its parent body. However, the size of the cores allowed these planets (particularly Jupiter and Saturn) to grab hydrogen and helium out of the gas cloud from which the sun was condensing, before the sun formed and blew most of the gas away. The metallic hydrogen layers in Jupiter and Saturn conduct electricity. Gas planets are made of layers of gas and liquid around a small, rocky core.
