Triton crashed into Neptune's moons

Abstract

The suspicions of planetary scientists that Neptune's moon Triton is an interloper from outside its system is discussed. Among them includes Robin Canup at the Southwest Research Institute in Colorado and Raluca Rufu at the Weizmann Institute of Science in Israel who used a series of computer simulations to figure out what the Neptune system was like before Triton barrelled in. They found that it probably had a moon system similar in total mass to Uranus's, but that didn't last long and adds that Triton crashed and destroyed the well-behaved satellite system that was before it.
