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 primary asteroid (Didymos A) is about 780 metres (2,560 ft) in diameter; the asteroid moon Dimorphos (Didymos B) is about 160 metres (520 ft) in diameter in an orbit about 1 kilometre (0.62 mi) from the primary. [15] The mass of the Didymos system is estimated at 528 billion kg, with Dimorphos comprising 4.8 billion kg of that total. [21]
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 ...
Nearly two years ago, the Double Asteroid Redirection Test spacecraft, or DART, collided with Dimorphos, a small asteroid that is the moon of a bigger space rock, Didymos, at about 14,000 miles ...
In the moments before NASA's DART spacecraft slammed into the asteroid Dimorphos in a landmark planetary defense test in 2022, it took high-resolution images of this small celestial object and its ...
65803 Didymos (provisional designation 1996 GT) is a sub-kilometer asteroid and binary system that is classified as a potentially hazardous asteroid and near-Earth object of the Apollo group. [a] The asteroid was discovered in 1996 by the Spacewatch survey at Kitt Peak, and its small 160-meter minor-planet moon, named Dimorphos, was
The last complete image of asteroid moonlet Dimorphos was taken by the DRACO imager on NASA's DART mission at a distance of about 7 miles (12 kilometers) and 2 seconds before impact.
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 ...
