Abstract

Critical observational constraints on the delivery of asteroids include orbital distributions, exposure ages and mineralogy. Orbital maturity in the inner solar system is indicated by the AM/PM distribution of meteorite falls and fireballs: Ordinary chondrites have short exposure ages, but their AM/PM fall statistics indicate significant orbital maturity. Hence, many may be collisional offspring of slightly larger parents that emigrated from the main belt. The required size distribution, extrapolated up to multi-km-size bodies, would also yield numbers of planet-crossing asteroids comparable to those astronomically observed. How multi-km Apollo-Amor-Atens are launched from the main belt is a major outstanding problem, as is identification of a parent population for the ordinary chondrites now that S-type asteroids once again are considered to be different from this most common kind of meteorite on the basis of reflectance spectroscopy. -from Authors
