> Thinking about it, my initial thought "part of the asteroid didn't get that hot" can't be right... I'm not sure about objects large enough to explode on impact, but smaller objects heat up and ablate, thus removing the heat, leaving the remaining object maybe not that hot. Probably tons of variables, including what the meteor is made of, the shape of it, angle of impact, etc...
