's outermost planet.
This water-ice surface is shared by some of Haumea's siblings that also appear to share the same orbit as the These simulations allowed the team to 'take apart' Haumea and then rebuild it from scratch. The aim of this was to understand the chemical and physical processes that shaped the dwarf planet.
This delivered a revised prediction of the dwarf planet's size and mass, and its density. It also delivered a prediction of Haumea's core size and density. Altering the features of Haumea in the models they developed allowed the team to run dozens of simulations viewing how small changes like increasing or decreasing the size of the dwarf planet changed its evolution.
This resulted in pieces breaking away from young Haumea, but these fragments didn't go on to become the Haumean family objects. This is because such a large impact would have knocked the pieces into far more scattered orbits than that possessed by the Haumean family bodies.
