65803 Didymos - Wikipedia
WEB65803 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
Didymos & Dimorphos - NASA Science
WEBOverview Asteroid Didymos and its small moonlet Dimorphos make up what’s called a binary asteroid system – meaning the small moon (Dimorphos) orbits the larger body (Didymos). The two asteroids are not a threat to Earth, but because they do pass relatively close to Earth, they were chosen as the target for NASA’s Double Asteroid […]

WEBJul 30, 2024 · In studying data collected from NASA’s DART (Double Asteroid Redirection Test) mission, which in 2022 sent a spacecraft to intentionally collide with the asteroid moonlet Dimorphos, the mission’s science team has discovered new information on the origins of the target binary asteroid system and why …
Didymos binary asteroid system: NASA's target for DART
WEBSep 27, 2022 · Didymos is a large asteroid around half a mile (2,560 feet or 780 meters) in length, while Dimorphos measures a mere 525 feet (160 m), according to the Johns Hopkins University Applied...
NASA Confirms DART Mission Impact Changed Asteroid’s Motion …
WEBOct 11, 2022 · Now, the investigation team has confirmed the spacecraft’s impact altered Dimorphos’ orbit around Didymos by 32 minutes, shortening the 11 hour and 55-minute orbit to 11 hours and 23 minutes. This measurement has a margin of uncertainty of approximately plus or minus 2 minutes.

WEBJul 30, 2024 · Scientists have analyzed images of the twin asteroids Didymos and Dimorphous taken by NASA's DART mission before it impacted the smaller space rock, revealing their age and origins.
NASA Study: Asteroid’s Orbit, Shape Changed After DART Impact
WEBMar 19, 2024 · DART’s target, the asteroid Dimorphos, orbits a larger near-Earth asteroid called Didymos. Before the impact, Dimorphos had a roughly symmetrical “oblate spheroid” shape – like a squashed ball that is wider than it is tall.
Mission Overview - dart.jhuapl.edu
WEBNov 24, 2021 · The Didymos system is an eclipsing binary as viewed from Earth, meaning that Dimorphos passes in front of and behind Didymos as it orbits the larger asteroid as seen from Earth. Consequently, Earth-based telescopes can measure the regular variation in brightness of the combined Didymos system to determine the orbit of Dimorphos.
