Contact binaries

The flattening of Ultima Thule and contact binary theory

contact binary theory Ultima Thule Arrokoth

The walking speed collision then sticking and melting together of contact binaries was not original predicted and the theory is still unexplainable for the flattened shape of Ultima Thule lobes. This was the first trans-Neptunian object other than the planetary systems we have photographed and done a fly by. It is absolutely guaranteed that lots more TNO’s like Arrokoth (Ultima Thule) will be even weirder and totally unexplainable.
