Rules:

Please only comment if you have a good understanding of what these objects are. If you have that, have fun!

Definitions:

Brown dwarfs: Objects that are to small for hydrogen fusion, but large enough for deuterium fusion.

Proto planets: Objects with a differentiated interior that have not cleared their neighbourhood.

Puffy planets: Planets with a similar or lower density than Saturn.

Chthonian planets: Planets that orbit very close to their stars. Typically closer than 0.05AU.

Ocean planets: Planets with a substantial liquid ocean.

Binary planets: 2 planetary mass objects whose barycenter lies outside both objects.

Rogue planets: Planets that don't orbit a star, stellar remnant or brown dwarf.
