A gas giant describes a planet that is not composed of mostly rock and other solid substances. Gas giants are almost entirely formed of various gases. These planets are not completely gas though. At the center, is what astronomers call a rocky center.
Why are these planets called gas giants and ice giants? The name âgas giantâ was coined in 1952 by science fiction writer James Blish to refer to all the giant planets. The four giant planets are huge gas balls, which is quite different than Earth and and other three rocky inner planets. Gas giants are primarily composed of gases, such as hydrogen and helium, and a much thicker layer of metallic hydrogen, along with a molten rocky core. Unlike rocky planets, gas giants do not have a well-defined surface, and there is no clear boundary between where the atmosphere ends and the surface begins.
