One possible explanation that's almost certainly not correct is that it was struck by an asteroidal fragment. Although this comet occupies the realm between Mars and Jupiter, its orbital inclination (19°) actually keeps 17P/Holmes well separated from most denizens of the asteroid belt. Moreover, counting the outbursts that occurred during and after its discovery in 1892, three collisions would be needed to explain all the activity.
