Kuiper Belt Collision Found; Possible Comet Source 68
siglercm writes "Astronomers have detected the remnants of an
ancient collision in the Kuiper
Belt, the region of bodies found outside of our solar system. The massive impact
between a nearly Pluto-sized body and one half as large created a 'collisional family' of objects; this
is the first such family identified in the Kuiper Belt. The largest body produced may cross
Neptune's orbit in the distant future, but it's possible that smaller objects created by the smash-up
have already fallen into the inner solar system as comets."

Wouldn't the result resemble asteroids rather than comets?

I was really dense in reading your post at first. I think I understand your question now, but please let me know if I've got it wrong.
This is a possible source of some (few) comets (if I understand correctly). I don't believe there's any assertion that all comets come from this collision. The main object is mostly rocky, but they say the trailing small ones are icy. It's possible that some of these smaller bodies may have been perturbed from their orbits and fallen into the inner solar system as comets.
