Шаблон:Short description

Шаблон:Use dmy dates Шаблон:Infobox planet Шаблон: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. Analysis of light-curve suggests that it is not a dwarf planet.[4]

Orbit and rotation

Like Pluto, Шаблон: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]

Шаблон:Mp has a significant light-curve amplitude of Шаблон:Val. The most likely value of the rotation period is Шаблон:Val.[6]

Physical characteristics

Шаблон: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 Шаблон:Val.[9] However, in 2012, this was reduced to Шаблон:Val after new Herschel Space Telescope observations.[10] In 2019, Шаблон: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 Шаблон:Mp are estimated at Шаблон:Val, with a volume-equivalent diameter Шаблон:Val.[8] Шаблон: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 7.5Шаблон:E kg.
