Rocky debris blasted away from the tiny asteroid Dimorphos when NASA’s DART spacecraft intentionally slammed into it in 2022 could create the first human-made meteor shower known as the Dimorphids, new study has found.

The space agency planned the DART, or Double Asteroid Redirection Test, mission to carry out a full-scale assessment of asteroid deflection technology on behalf of planetary defense. NASA wanted to see whether a kinetic impact — such as crashing a spacecraft into an asteroid at 13,645 miles per hour (6.1 kilometers per second) — would be enough to change the motion of a celestial object in space.

Neither Dimorphos or the large parent space rock it orbits, known as Didymos, pose a danger to Earth. Still, the double-asteroid system was a perfect target to test deflection technology because Dimorphos’ size is comparable to asteroids that could threaten our planet.

Astronomers have used ground-based telescopes to monitor the impact’s aftermath for nearly two years, and they determined that the DART…
