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 ...
When NASA’s Double Asteroid Redirection Test spacecraft intentionally slammed into the asteroid Dimorphos in September 2022, the impact may have caused “global deformation” of the space rock ...
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 ...
Hera is a spacecraft developed by the European Space Agency for its space safety program. Its primary mission objective is to study the Didymos binary asteroid system that was impacted four years earlier by the NASA Double Asteroid Redirection Test (DART) spacecraft and contribute to validation of the kinetic impact method to deviate a near-Earth asteroid from a colliding trajectory with Earth.
In September 2022, Nasa’s Double Asteroid Redirection Test (Dart) spacecraft collided with Dimorphos in the first test of deflecting an asteroid.
