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.
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.
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. This image made available by NOIRLab shows a plume of dust and debris blasted from the surface of the asteroid Dimorphos by NASA's DART spacecraft after it impacted on Sept. 26, 2022, captured by the U.S. National Science Foundation's NOIRLab's SOAR telescope in Chile. The expanding, comet-like tail is more than 6,000 miles long.
The computer modelling measured different possible pathways and velocities of the particles across the solar system as well as how radiation released by the sun might affect the motion of the particles. The study authors consider the possibility of the Dimorphids meteor shower reaching Earth unlikely, but they can't rule it out, Peña Asensio said."The resulting meteor shower would be easily identifiable on Earth, as it would not coincide with any known meteor showers," he said by email.
