Dwarf gas giant planet
WebThe line between brown dwarf and gas giant - to my knowledge - has not been drawn. Personally, and I think I remember reading somewhere , the general consensus is that around 10-20 M J is the boundary between a gas giant planet and brown dwarf, but I think it's fairly arbitrary, much like what's a planet vs. minor planet, Kuiper belt object ...
