Detailed explanation-1: -The giant gas planets Jupiter, Saturn, Uranus, and Neptune have thick atmospheres of mainly hydrogen and helium that gradually increases in density, with possibly a rocky core inside (see Interiors of the Giant Planets).
Detailed explanation-2: -The planet Jupiter, Saturn, Uranus and Neptune are sometimes called the Gas Giants because so much of the mass of these planets consists of a gaseous atmosphere. These bodies generally lie far from the sun.
Detailed explanation-3: -Interiors. The cores of all four jovian planets are made of some combination of rock, metal and hydrogen compounds. Jupiter and Saturn have similar interiors, with layers extending outward of metallic hydrogen, liquid hydrogen, gaseous hydrogen, and topped with a layer of visible clouds.
