In 2022, we all watched the NASA DART spacecraft ram into Dimorphos, the small moonlet of asteroid Didymos.
Study of data from that mission has now provided clues on how the moonlet might have formed.
This fascinating visualization demonstrates how the spin-up of asteroid Didymos could have led to the growth of its equatorial ridge, launching of rocks/rubble into orbit and subsequent coalescing and formation of Dimorphos ~300,000 years ago.

  NASA’s DART Mission Sheds New Light on Target Binary Asteroid System - NASA Science
  
  In studying data collected from NASA’s DART (Double Asteroid Redirection Test) mission, which in 2022 sent a spacecraft to intentionally collide with the asteroid moonlet Dimorphos, the mission’s science team has discovered new information on the origins of the target binary asteroid system and why the DART spacecraft was so effective in shifting Dimorphos’ orbit. In five recently […]
