It is speculated that an object thumped Pluto and using computer simulation they suggest it may have created Charon (which is almost the size of Pluto).

Chewing over that piece of wisdom we may note Japanese researchers from Keio University are involved – and simulation. While they were looking for the results of a supernova explosion out there in space they came across a small molecular cloud with an unexpected motion. It has been nicknamed the Bullet as it has a speed of 100km a second. In other words, it exceeds the speed of light. We are told it was impossible to generate such an energetic cloud under ordinary environments.
