Gas giant

Gas giants are a grouping of planets, often huge, due to having a thick layer of gases in their atmosphere: normally obscuring the surface. Most gas giants are in reality very small, yet dense, with such great gravity that they bear very thick atmospheres. Due to their immense gravity, gas giants often have many moons, some, due to tidal friction, are warm enough to support a substantial quantity of fluid medium. Life on gas planets scarcely achieves sapience, due to the inability to manufacture tools and devices, in the absence of solid surfaces. The moons of gas planets often host abundant life.
