Impact bombardment chronology of the terrestrial planets from 4.5 Ga to 3.5 Ga [PDF]
Icarus (New York, N.Y. 1962), 2019 Subsequent to the Moon's formation, late accretion to the terrestrial planets modified their silicate crusts and mantles. We combine dynamical N-body and Monte Carlo simulations to determine impact probabilities, impact velocities, and expected mass ...
