Solar System Asteroid Belt Best Explained as Remnants of Planetary Formation Collisions, not Pristine, Remnant Planetesimals
Erosive Hit-and-Run Impact Events: Debris Unbound
Authors:
Sarid et al
Abstract:
Erosive
collisions among planetary embryos in the inner solar system can lead
to multiple remnant bodies, varied in mass, composition and residual
velocity. Some of the smaller, unbound debris may become available to
seed the main asteroid belt. The makeup of these collisionally produced
bodies is different from the canonical chondritic composition, in terms
of rock/iron ratio and may contain further shock-processed material.
Having some of the material in the asteroid belt owe its origin from
collisions of larger planetary bodies may help in explaining some of the
diversity and oddities in composition of different asteroid groups.
