Would anyone like to explain why this planet would have a temperature of 400C (I was picturing it being really cold)? Is this because of its mass/size, more related to its gaseous composition or both?

- scottscanlon 14y agoah, thanks for that.
- wcoenen 14y agoI think that the news here is that is has been determined that it is not a brown dwarf. See the paper[1] for more details. Though I'm not sure why the distinction between giant planet vs cold tiny star is so important. [1] http://arxiv.org/abs/1210.0305 http://arxiv.org/abs/1210.0305
