| Abstract: | Post-bombardment periods of increased impact flux on Earth are probably due to the decay of captured Apollo object group orbits. The origin of the Messier binary impact structure on the Moon implies the breakup of a single impactor as the origin of a Cretaceous/Tertiary multiple impact. |
