Looks like a giant dog bone.
It reminds me of radar images of Kleopatra.
But, Kleopatra is an asteroid, not a comet.
I guess the new definition of a comet is?
If it looks like a small rubble-pile asteroid,
and it spits, and keeps on spitting, it's a comet. 😉
BTW, if that were a dog bone, I'd hate to see the dog. 😁 😁
