Perhaps a ~17% change is not significant on the scale that we inhabit (20C today depending where you are), but 1000C is a lot of degrees.

- jlgreco 13y agoIndeed. It seems this new estimate puts it into "surface of the sun" territory (5700-8800K).
- samstave 13y agoI know nothing about this, but I wonder if core temp would have any impact on the habitability of a planet. We know there is the habitable zone around a star, I wonder if that body in that zone would also need a certain core temp to support life.
- jlgreco 13y agoI don't know much about this, but my understanding is that a hot core is not itself something that life particularly needs. The effects of that hot core however (Spinning core to make a magnetosphere? Volcanic activity changing atmospheric chemistry?) are probably more important. On the other hand, a hot core gives you deep sea thermal vents. Although I think the current prevailing theories don't have life originating near those on Earth, a hot core is certainly essential to life down there and, perhaps on another world, life could originate there.
