Notes. The first column N gives the number of impacts per Myr (1.5% of the bodies collide), rP = D/ 2 the impactors’ radii representative for the size intervals, and Ėkin,all the kinetic energy of all impactors of a certain size interval based on basalt asteroids with average density ρ = 2.7 g cm-3 and 10 km s-1 impact velocity.
