There's the Vernor Vinge story "A deepness in the sky", wherein the 
protagonists evolved around a sun that was hot only a few decades out of 
each several centuries and managed to hibernate through the cold times. I 
imagine something like that with a comet could work out. Hard to see how it 
would *evolve*, mind, unless the body started out in a close orbit that got 
more and more eccentric over time somehow.

Weightlessness?

I'm not sure that's as much of a problem as you think it is for anything 
other than fish.  Why do you think the fact that it floats is important?

Also, it floats in part because it's a polar molecule (i.e., electrically 
asymmetrical), which may very well be more important than the result of 
floating.
