I just disabled temperature in the Celestia trunk. I left the code in place, but commented it out.
Reading through recent forum posts, I was reminded about the temperature display for planets. I agree with Andrew's argument in this thread:that it's time to remove it from the selection info in the text overlay. Can anyone offer a compelling argument to keep the temperature in the selection info? This sort of data seems like the sort of thing that could be calculated and displayed by a script for whomever was really interested in it.
