Class A gas giant

For other uses, see Class A.

Class A Gas Giant
Jupiter
Classification:	radiant gas giant
Surface:	tenuous, may not be present
Atmosphere:	possible methane concentration

In planetary classification, a class A gas giant is a type of planet. As the name describes, the planet is generally composed of a tenuous gas concentration, with or without a more solid subsurface or core. In many cases, methane composes a significant amount of the planetary atmosphere. In particular among gas giant planets, the class A worlds of this type are radiant of heat and some energy, differing in this respect from the class B gas giant. Jupiter is an example of a class A radiant gas body. Some notations on this classification list worlds of this type as being similar to unborn stars that have failed to ignite into nuclear fusion.

This classification should not be confused with the class A geothermal planet described in ST reference: Star Charts.
