(provisional designation ) is a trans-Neptunian object (TNO) estimated to be about 250 km in diameter. It was discovered on 9 September 2005 by Andrew Becker, Andrew Puckett and Jeremy Kubica at Apache Point Observatory in Sunspot, New Mexico.
See main article: Haumea family. Based on their common pattern of IR water-ice absorptions, neutral visible spectrum, and the clustering of their orbital elements, the other KBOs,, and appear to be collisional fragments broken off the dwarf planet .
The surface is covered by water ice as attested by deep absorption at 1.5 and 2 μm in the infrared spectrum and neutral (i.e. non-red) colour. Scattering models reveal that the observed water ice is, at least in a significant fraction, crystalline and organics, detected on the surface of many TNOs, are completely absent.These physical and orbital characteristics common with Haumea led to suggestion that is a member of the Haumea collisional family. The object, together with other members of the family (and), would be created from ice mantle ejected from the proto-Haumea as result of a collision with another large (around 1660km (1,030miles)) body.
