[meteorite-list] Comet Holmes, always the same........

[Chris Peterson]

All periodic comets eventually lose their volatiles. The result is an 
extinct comet, although nobody knows exactly what that means... an 
asteroid? a loose clump of rocky material? There are asteroids which are 
believed to be extinct comets (3200 Phaethon, for instance, the parent 
body of the Geminids).

Holmes is a Jupiter class comet, which means it isn't in a particularly 
stable orbit. It's probably only been in the inner Solar System for a 
few thousand years, maybe less. It also doesn't seem particularly active 
in general- the two known outbursts excepted. But anytime it's at all 
active, it is losing material, and it can't do that forever. It could 
also be perturbed into an orbit keeping it far from the Sun, in which 
case it would never be active and therefore wouldn't lose more material, 
or much closer (or even into) to the Sun, in which case it would rapidly 
lose its volatiles.
