Planets

There are three main categories of planets: Solid planets, water giants and gas giants. Even moons are considered as planets.

Gas Giants

Image	Class	Exploration Value (with detailed surface scanner?)	Rarity	Description
File:Gas-Giant-Class-I.png Class I Gas Giant	I	1,000 - 1,500cr	Rare	Class I or Jovian gas giants have primarily hydrogen and helium atmospheres. Coloration comes from clouds in the upper atmosphere of ammonia, water vapour, hydrogen sulphide, phosphine and sulphur. The temperature at the top of their upper cloud layers is typically less than 150 K.
	II	5,000cr	Very rare
File:Gas-Giant-Class-III-180px.png Class III Gas Giant	III	1,000 - 1,500cr	Rare
	IV	1,000 - 1,500cr	Rare
	Water giant	?
File:Gas giant with ammonia based life.png Gas giant with ammonia based life	Gas giant with ammonia-based life	1,000 - 1,500cr	Very rare	Gas giant with ammonia-based life. This is primarily a hydrogen and helium-based atmospheric gas giant, but a little below the surface cloud layers,life exists based in the ammonia-cloud layer. The chemistry of this gaseous region is far from equilibrium, with a surprising excess of oxygen and many carbon-based compounds giving it some vivid colours. As with many such gaseous living systems, it is underpinned by vast quantities of free-floating radioplankton - tiny carbon-based algae, each retaining small quantity of liquid ammonia, extracting their energy from the intese radiation flux.
