Beyond Neptune sits one of the stranger dwarf planets, Haumea. This icy rock receives its flattened dinosaur egg shape from its lightning-fast rotation -- a day only lasts four hours there. But it gets even weirder. New evidence is consistent with the presence of a ring. A tiny ring for a tiny planet.
A University of Michigan doctoral student has logged two pieces of evidence that may support the existence of a planet that could be part of our solar system, beyond Neptune.
Rugby ball-shaped dwarf planet with two moons also has a ring around it and orbits in the outer solar system A ring has been discovered around one of the dwarf planets that orbits the outer reaches of the solar system. Until now, ri...
Observations of the distant dwarf planet Haumea constrain its size, shape and density, and reveal an encircling planetary ring. The discovery suggests that rings are not as rare in the Solar System as previously thought. See Letter ...
Scientists have discovered a ring around Haumea, a dwarf planet located beyond Neptune. The ring lies in the same plane as its equator and as the orbit of its outer moon, Hi'iaka.
