Is there some SIZE differences between an asteroid and a comet? I think it DOES matter what you call Chiron, as where it might have volatiles, it got into the category of asteroid for some reason! Chiron the asteroid was discovered when it had no coma from volatiles, so it was BIG ENOUGH TO BE REFLECTING SUNLIGHT, right? Thus the asteroid designation. How big is Chiron estimated to be, and how does this compare to the dirty snowball that Hale-Bopp is being called?
