@cell__im @JordanT12081 @ASI_spazio DART and the Didymos are each in separate orbits around the Sun. DART’s orbital speed has been about 67,000 mph relative to the Sun. Because the Didymos system is also moving, the relative speeds of DART and Dimorphos at the time of impact is 14,000 mph relative to each other. — PolitiTweet.org
