Model of Didymos system

Simulated image of the Didymos system, derived from photometric lightcurve and radar data. The primary body is around 780 m in diameter and the moonlet or Didymoon is approximately 160m across. They are separated by just over a kilometre. The primary body rotates once every 2.26 hours while the tidally locked moonlet revolves about the primary once every 11.9 hours.
