[meteorite-list] Average size of craters across the solar system?

I was just thinking about this, wondering if anyone has tried to compare average sizes of craters across bodies in the solar system? I was thinking along the lines that, since orbital velocity is higher the closer an object is to the sun, then there should be more bang for the buck for impactors.

Hi Darren: Lots of other factors going on: Extra velocity caused by the gravity of the impacted body. Composition of the surface being hit. Composition/density (and thus mass) of the impactor. Surface processes that will affect the loss of craters or their just fading away. At some point,
