(provisional designation ) is a trans-Neptunian object. Light-curve-amplitude analysis shows only small deviations, suggesting is a spheroid with small albedo spots.[4] Measurements by the Spitzer Space Telescope estimate that it is 461 ± 45 km in diameter.[2] It was discovered in 1999 by Chad Trujillo and Jane X. Luu. It is possibly a dwarf planet.[5]
orbit is in 2:5 resonance with Neptune's.[1] Spectral analysis has shown traces of ice.[6]
