Debris flying immediately after DART collided with Dimorphos. (NASA DART team and LICIACube) In 2022, NASA made history, deliberately smashing a spacecraft into an asteroid to see if it could alter ...

It is the first man-made object to have shifted the orbit of a naturally occurring entity in space.

It provides a dynamic, time-resolved view of planetary transformation, a missing link between young inflated worlds and the compact sub-Neptunes that populate the galaxy.

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.

Great question! Assuming you’re referring specifically to the orbital period — in other words, how long comets take to make one revolution around the Sun, or a cometary “year” — according to basic ...
