Group 8 The Gas Giant Planets

Do you know what Gas Giant Planets are ?

Jupiter, Saturn, Uranus, and Neptune are often called "Gas Giants." They are basically gigantic gas balls compared to Earth and the other three rocky inner planets, or to the icy "dwarf planets.The four giant planets are comprised mostly of an outer layer of molecular hydrogen and helium and a much thicker layer of metallic hydrogen. However, each may have a small solid core as large as three to 20 Earth masses at their center. Sometimes they are called "Jovians" because Saturn, Uranus, and Neptune are considered to be very similar to Jupiter.
