Of course the ring, the rapid rotation, and the odd shape of Haumea could all point to a possible impact. The problem with that idea is that Haumea isn't the only small body that has recently been ...

This puts Haumea in a class of its own in terms of astronomical bodies with rings. In our solar system, most of the ringed planets are gas giants, not rocky planets.

This and other findings on Haumea are reported in a Nature paper by Ortiz et al. (2017) entitled “The size, shape, density and ring of the dwarf planet Haumea from a stellar occultation ...

Astronomers have observed an occultation of a distant star to get a better look at the little-known dwarf planet Haumea, which orbits the Sun beyond Neptune. Scientists were able to pin down the ...
