These planets are essentialy made of water, mostly in a supercritical state due to the hot temperature and pression (around 1000 atm). These planets are essentialy seens as "mini-neptunes". Most of these planets atmosphere are composed of H2O and others gases such as CH4, NH3 etc... they are also obviously very wet.
This class is classed between sauna planet and ice giants
== Mass and size ==
The mass and size can vary a lot, you can see mini-neptunes with the mass of earth and others with like 3 times the mass of earth, same for the radius. Only thing it need is a very dense atmosphere for enough pressure.
== On space engine ==
These planet on space engine are classed as mini-neptunes and subneptunes. You can find them easily by just searching a bit.
