NASA’s DART mission precisely measured changes in asteroid Dimorphos’ orbit and the Didymos system’s heliocentric motion using radar, stellar occultations and space observations.

A new study shows that, not only did the agency’s 2022 DART mission shift the orbit of the moonlet Dimorphos, it also changed the path of its parent asteroid around the sun.

Now we know we also changed Didymos's orbit around the sun, and we did so without even touching it. We knew the impact on Dimorphos − which is about 160 meters across compared with Didymos's 765 ...
