Hera Sees Two Asteroids: One Dot Becomes Two | Science Made Simple

Discover how ESA's Hera spacecraft saw the Didymos and Dimorphos asteroids as two separate objects for the first time. Learn why the pair previously looked like a single dot, how the 18 October image from about 1,280 km revealed tiny Dimorphos, and how NASA's 2022 DART impact shortened Dimorphos's orbit by about 33 minutes — and why Hera's close-up study matters for planetary defence.
