Jovian worlds are massive gas or ice giants.
When these are fleshed out, they should probably include reference to Sudarskey's gas giant classification.
Sub Jovian Class
These are smaller Jovian worlds which have the bulk of their mass concentrated in a rocky or icy core. They still have extensive gaseous atmospheres however. Mass can be from 0.03 to 0.48 times that of Jupiter.
- Sokarian - These are hot worlds close to their star, with silicate clouds in the upper atmosphere.
- Poseidonic - These are within the snowline with large quantities of water vapour.
- Neptunian - These are found in the outer system, which may have methane in the upper atmosphere. They can be blue or green in colour.
Dwarf Jovian Class
There are smaller Jovian worlds which have the bulk of their mass concentrated in the gaseous atmosphere, and have only a minimal core. Mass can be from 0.06 to 0.8 times that of Jupiter.
- Osirian - Hot worlds close to their star with silicate atmospheres.
- Brammian - Orbit within the snow line and have large amounts of water vapour.
- Khonsonian - Just outside of the snow line with ammonia atmospheres, often with ammonia life.
- Saturnian - Beyond the snowline with dynamic atmospheres.
Meso Jovian Class
These are typical Jovian worlds, with masses ranging from 0.7 to 2.5 times that of Jupiter.
Super Jovian Class
There are massive Jovian worlds which range from 2.5 times to 13 times that of Jupiter. At the upper end, the line between Super Jovian and Brown Dwarf becomes blurred.
- SuperJunic - Hot worlds with silicate atmospheres.
- SuperJovic - Colder worlds beyond the snow line.
These are the exposed cores of Jovian worlds which have lost their gaseous atmosphere. They will tend to have a mass between 0.015 to 0.24 times that of Jupiter.
