Dimorphos has a diameter of 177 meters (581 ft) across its longest extent and it was the target of the Double Asteroid Redirection Test (DART), a NASA space mission that deliberately collided a spacecraft with the moon on 26 September 2022 to alter its orbit around Didymos.
The collision shortened Dimorphos' orbit by 32 minutes, greatly in excess of the pre-defined success threshold of 73 seconds. [7] [8] [9] DART's success in deflecting Dimorphos was due to the momentum transfer associated with the recoil of the ejected debris, which was substantially larger than that caused by the impact itself.

Didymos is a binary asteroid with a satellite in its orbit. The minor-planet moon, named Dimorphos, [18] moves in a mostly circular retrograde orbit [19] with an orbital period of 11.9 hours. [11] [d] It measures approximately 160 meters (520 ft) in diameter compared to 780 meters (2,560 ft) for its primary (a mean diameter-ratio of 0.22). [20]
The Double Asteroid Redirection Test spacecraft, or DART, collided with Dimorphos, a small asteroid measuring 525 feet in diameter that is located roughly 7 million miles from Earth, at 7:14 p.m ...
The team believes that 1% of Dimorphos’ entire mass was kicked out into space due to the impact, while 8% of the asteroid’s mass was shifted around. “Hera will probably not be able to find ...
The mission succeeded in changing the orbit of Dimorphos around Didymos by 33 minutes, proving the concept of asteroid deflection. ... NASA or perhaps the Space Force should build a prototype and ...
When NASA sent its DART spacecraft to slam into the asteroid Dimorphos in 2022, the U.S. space agency demonstrated that it was possible to change a celestial object's trajectory, if needed, to ...
The DART mission activated Dimorphos under precisely known and carefully observed impact conditions, enabling the detailed study of the formation of an active asteroid for the first time. [ 17 ] [ 18 ] Observations show that Dimorphos lost approximately 1 million kilograms after the collision. [ 19 ]
