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.
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 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]
In 2022, NASA launched the Double Asteroid Redirection Test (DART) spacecraft, whose sole goal was to fly 7 million miles to the 525-foot asteroid Dimorphos, and crash into it at 14,000 miles per ...
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 ...
Asteroid 2024 YR4, a 50- to 90-meter-wide Earth-approaching object, is likely not going to hit our planet in 2032. ... The mission succeeded in changing the orbit of Dimorphos around Didymos by 33 ...
In September 2022, Nasa’s Double Asteroid Redirection Test (Dart) spacecraft collided with Dimorphos in the first test of deflecting an asteroid.
