Feature names for #AsteroidDonaldjohanson. According to astrafoxen on bsky, they're appropriately named after archeological sites and hominin fossils.

The #LucyMission posted yesterday the highest resolution photo they got of the whole #AsteroidDonaldjohanson (there are higher res partial closer photos)
They have some other goodies in their gallery
https://lucy.swri.edu/DonaldjohansonImageGallery.html#StereogramsPersonally, I was still a bit confused by the wavy ridge of the minor lobe, but with some color editing, it now looks to me that we are seeing part of the inner wall of a huge crater hollowing the lobe?
