According to astronomer S.A. Phinney, kicking a rock hard enough to free it from Earths gravity would require a meteorite capable of making a crater more than 60 miles across. Moreover, even if Earth rocks were freed by meteorite impact, Marss orbit is much larger than Earths, so Phinney estimates that the probability of these rocks hitting Mars is about one-tenth as great as that of Marss rocks hitting Earth.
