Impacts of small celestial bodies, in terms of energy density, occupy the range between ordinary chemical high explosives and nuclear explosions. The high initial energy density of impact gives them some features of an explosion (shock waves, melting and vaporization, mechanical disruption of target rocks).

Comet craters versus asteroid craters
Advances in Space Research, 1991Abstract The assumptions used to determine whether active comets or earth-crossing asteroids currently dominate the terrestrial cratering rate are reviewed and intercompared. The principal sources of uncertainty are the number and mass distributions of earth-crossing bodies, the adopted crater-diameter scaling law, and the question whether the ...

Abstract Recent observational evidence emphasizes the importance of craters as a prominent surface characteristic of the smaller planetary bodies in the solar system. Craters of similar appearance may have very diverse origins. An initial assumption as to the type of origin should not influence an impartial and detailed physical study of any given ...
