Abstract
Comparison of three-dimensional particle shape (3 axial ratio) distributions between asteroid Itokawa and the moon shows that the both distributions are statistically distinguished. They are also distinguished from that of particles produced by catastrophic impact experiments, and the differences are reflected by impact conditions and/or later regolith evolution.
