Template:Mp is a trans-Neptunian object discovered by the Near-Earth Asteroid Tracking program on 14 November 2003.[1] Like Pluto, it is in a 2:3 orbital resonance with Neptune[2][3] and is thus a plutino. It has an elongated ellipsoidal shape.[4]
Orbit and rotation
Like Pluto, Template:Mp 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.[5]
Template:Mp has a high light curve amplitude of Script error: No such module "val"., indicative of an elongated, non-spherical shape.[4] The most likely value of the rotation period is Script error: No such module "val"..[6]
Physical characteristics
Template:Mp has a moderately red surface with a moderately red color indices B−V=0.93, V−R=0.59.[7] Its geometrical albedo is about 0.13.[8]
In 2007, its diameter was initially estimated by the Spitzer Space Telescope at Script error: No such module "val"..[9] However, in 2012, this was reduced to Script error: No such module "val". after new Herschel Space Telescope observations.[10] In 2019, Template:Mp was found to be ellipsoidal in shape based on stellar occultations that occurred in 2013 and 2014;[8] the light curve derived from the occultations suggests that this plutino is not in hydrostatic equilibrium and hence not a dwarf planet.[11] The dimensions of Template:Mp are estimated at Script error: No such module "val"., with a volume-equivalent diameter Script error: No such module "val"..[8] Template:Mp has no known satellite that can be used to directly determine its mass, but assuming a density of 1 g/cm3, typical of mid size TNO's,[12] gives a mass estimate of about 7.5Template:E kg.
