Rubin Observatory spots an asteroid that spins fast enough to set a record

Completing a full rotation in under 2 minutes at 710 meters diameter is insane. The fact that it holds together at that spin rate tells us a lot about its composition - it can't be a rubble pile.

Rubin Observatory is already delivering results in just 7 nights of commissioning data. The full 10-year survey is going to be incredible for solar system science.
