Interesting question to think about.
We know that there are lots of comet bodies in the Oort cloud and we know that even in the near absolute zero temperatures evaporation does take place. Comets are usually covered in dust, which slows down this evaporation, but let's consider clear body.
How much time will it take to completely evaporate average comet body (of wafer ice) 10x5 km? Comet does not go around the sun - just sitting in the Oort cloud in the edge of the Solar System. Any good approximations?
