摘要

•Absolute model formation ages of Occator crater range between 1.6 and 63.7 Ma.•Previous studies of Occator crater suggest age errors that are underestimated.•Impactor/crater scaling parameters have the largest influence on age dating results.•Ballistics on low gravity, quick rotating bodies allow for self-secondary cratering.
