is a trans-Neptunian object discovered by the Near-Earth Asteroid Tracking program on 14 November 2003. Like Pluto, it is in a 2:3 orbital resonance with Neptune and is thus a plutino. It has an elongated shape with an estimated volume-equivalent diameter of 525 km.
Like Pluto, is locked in the 3:2 mean-motion resonance with Neptune, although its orbit is both less inclined and significantly less eccentric than Pluto's.
has a high light curve amplitude of , indicative of an elongated, non-spherical shape. The most likely value of the rotation period is .
has a moderately red surface with a moderately red color indices BâÂÂV=0.93, VâÂÂR=0.59. Its geometrical albedo is about 0.13.
In 2007, its diameter was initially estimated by the Spitzer Space Telescope at . However, in 2012, this was reduced to after new Herschel Space Telescope observations. In 2019, was found to be ellipsoidal in shape based on stellar occultations that occurred in 2013 and 2014; the light curve derived from the occultations suggests that this plutino is not in hydrostatic equilibrium and hence not a dwarf planet. The dimensions of are estimated at , with a volume-equivalent diameter . Further observations of occultations refined the estimate to ÃÂ ÃÂ km, with a mean diameter of .
has no known satellite that can be used to directly determine its mass, but assuming a density of 1 g/cm<sup>3</sup>, typical of mid size TNOs, gives a mass estimate of about 6.5 kg.
