Primarily, an analysis of the craters and surface strength on Didymos indicated it formed about 12.5 million years ago, while its smaller companion, Dimorphos, formed about 300,000 years ago.

Dimorphos and Didymos do not pose an actual threat to Earth. The spacecraft collided on Sept. 26, 2022, at about 14,000 miles per hour into Dimorphos, an asteroid that was about 560 feet wide, ...
