2014 MU69 has two nearly-spherical lobes and is a contact binary. The collision between the two lobes happened at a low relative velocity, causing little damage to the resulting object. The "neck" between the lobes contains brighter material which appears to be dust that has settled down the slopes that run towards the point of contact.

The pictures of Pluto blew me away. Can't wait for the detailed pictures of this thing, although I'm guessing it won't be as cool looking as Pluto was.

It's the coolest (literally) cleavage we've ever seen.
