Asteroids with small moons can exchange rocks and dust in slow, gentle collisions
SMRTR summary
NASA's DART spacecraft captured the first direct evidence of asteroids and their moons exchanging rocks and dust through gentle collisions, revealing fan-shaped streaks on Dimorphos' surface caused by material drifting at just one foot per second from its parent asteroid Didymos. This discovery proves that binary asteroid systems actively reshape themselves over millions of years through these "cosmic snowball" interactions, providing crucial insights for predicting asteroid behavior near Earth.
