Mondo Knows Facts
DART nudged an asteroid onto a new orbit
The 2022 impact shortened Dimorphos's orbit around Didymos by 32 minutes NASA crashed a 570 kilogram spacecraft into the small moonlet Dimorphos in September 2022 at about 6 kilometres per second. Telescopes on Earth timed the resulting change in its orbit around the larger asteroid Didymos. The shift was far larger than the impact alone would explain, because debris flew off and pushed harder. It sits in Mondo's space collection, one of 200 facts that each trace back to the reference below.
