Asteroidal Source of Meteorites

The evolution of asteroidal orbits initially near the Kirkwood Gap at the 1:2 commensurability with Jupiter's period provides a mechanism for the production of meteorites from the asteroid belt without excessive velocity change. The resulting yield (sim 109 grams per year) and the orbital elements of Earth-crossing objects are in agreement with observational data on meteorites.
