is a trans-Neptunian object and member of the Haumea family, located in the Kuiper belt in the outermost region of the Solar System. It was discovered on 24 October 2003, by astronomers of the Spacewatch survey project at Kitt Peak Observatory, Arizona. The object may also be a non-resonant cubewano.
Orbit and physical characterization
orbits the Sun at a distance of 38.3–49.8 AU once every 292 years and 5 months (semi-major axis of 44.05 AU). Its orbit has an eccentricity of 0.13 and an inclination of 27° with respect to the ecliptic. Precovery images have been identified back to 2002.
Its diameter is around . Two rotational lightcurves of the object gave a rotation period of 6 and 10.61 hours with a brightness amplitude of 0.1 and 0.09 in magnitude, respectively (). It has a spectral type of BB, with a grey/blue rather than red color.
Origin
Based on their common pattern of infrared water-ice absorption and the clustering of their orbital elements, appears to be one of the collisional fragments broken off the dwarf planet . The neutral color of the spectrum of these objects in the visible range evidences a lack of complex organics on the surface of these bodies that has been studied in detail for the surface of Haumea.
