Well, this is actually what I meant
, emitting more than received.
I was not sure about other than Jupiter though, but I should have guessed..
So, lets say that the excess energy, radiated by those bodies need to be generated by nuclear fusion processes, to consider them stars (or companion stars). This way we can still have all our planets remain planets
