NASA’s DART Mission Did More Than Just Nudge an Asteroid, Study Says
Gizmodo • • general
Key Points:
- NASA's DART spacecraft successfully altered the orbit of asteroid moonlet Dimorphos around its larger companion Didymos, demonstrating humanity's ability to change a celestial object's trajectory through kinetic impact.
- New analysis reveals that the DART impact also slightly changed the binary asteroid system's orbit around the Sun, marking the first time an asteroid's solar orbit has been altered by human intervention.
- The change in Dimorphos's solar orbit was minute—a slowdown of 11.7 micrometers per second—resulting in a 0.15-second shortening of its 2.1-year solar orbit, proving the kinetic impactor technique can affect an object's path around the Sun.
- Further detailed observations are needed to fully understand the impact's effects
