Probable dwarf planet cubewano located at in the edge of the Kuiper Belt. Thought to be one of the largest KBOs found (2/3 Pluto's size) before Eris. It was found to be much more reflective than expected (18%), thus smaller than Ceres. This made it possible that Pluto could be much larger in comparison to most KBOs than thought. It was later found to be larger by the Spitzer, 734 km. It is red with no sign of water ice. Mike Brown considers it highly likely to be a dwarf planet.
