In retrospect, given who it is named after, it really should not be a surprise that it looks so much like a bone.

Contact binary + rubble pile? It's wild how much it looks like Toutatis.

Binary formation as a natural outcome of pebble cloud collapse is the conclusion of Robinson et al. (2020), Nesvorny et al. (2021) and Polak & Klahr (2023) using rather distinct numerical methods. These groups can't resolve contact binaries yet, but the velocity dispersions are low enough to work.

yes please do! and what about that neck region? looks like ice cream cones stacked in each other. what gives?

and it seems to me smoother than other asteroids in its size class? or is that cuz LUCY didn't fly too close? do you think we are going to get higher res images?

barrygoldman1.bsky.social•14 days ago
