Oh yeah, and the matter of "so how big is it?" is something I've avoided as video games do tend to compress things into a much smaller size than the "true" version would occupy, but I have absolutely no idea. Given the climate differences, maybe a couple of thousand miles top to bottom, but it could be more or it could be (much) less.
I'm also aware that one shouldn't read too much into climate e.g. Sentinel Island, as I'm currently playing Ego Draconis again and have been reminded that it was a green and pleasant land much like Broken Valley and Ferol (in fact probably very much like them, so for "pleasant" also read most *un*pleasant with lots of things trying to kill you!) and it was the dude with the creepy nose who made it red and barren. That said, apart from the volcanic activity it doesn't look all that warm to me, whereas Yuthul Gor does seem pretty scorchio.
