Etymology

From translingual Dimorphos, from Ancient Greek δίμορφος (dímorphos), from δί- (dí-)+μορφή (morphḗ)+-ος (-os); Literally, “having two forms”. From being the target of the DART (Double Asteroid Redirect Test) space mission, which impacted its surface, thereby having a form prior to the impact and another after the impact. Compare English dimorphous, Latin dimorphus.
