Abstract: | We have produced top ten ranked lists of impact velocity, mainbelt asteroid region dwell times and impact probabilities for
a selection of short period comets. The comet with the combined highest ranking with respect to impact probability and impact
velocity is Comet C/1766 G1 Helfenzrieder. Since it is not clear that this comet still exists, the highest ranked, presently
active, comet with respect to the likelihood of suffering impacts from meter-sized objects while in the main belt asteroid
region is Comet 28P/Neujmin 1. We find no evidence to support the existence of a distinctive sub-set of the short period comets
liable to show repeated outburst or splitting behavioursdue to small body, meter-sized, asteroid impacts.
