Шаблон:Infobox planet

Шаблон:Mp, also written as 2003 UZ413, is a trans-Neptunian object (TNO) with an absolute magnitude of 4.38.[1] It is in a 2:3 orbital resonance with Neptune, thus it is classified as a plutino.[2] There are indications it may be dense enough to be a dwarf planet. It was given the minor planet number 455502 on 22 February 2016.[3]

Шаблон:Mp has been observed 79 times over 15 oppositions, with precovery images back to 27 July 1954.[4]

Orbit and rotation

Шаблон:Mp is in a 2:3 resonance with Neptune, which means that when it makes two revolutions around the Sun, Neptune makes exactly three.[2]

The object rotates very fast. In fact, with a period of about 4.13 hours, it is the fastest rotator known in the Kuiper belt after Haumea.[5][6]

Physical characteristics

The mean diameter of Шаблон:Mp is estimated to be Шаблон:Val, assuming a low albedo.[1]

Given its rapid rotation, it must have a density higher than Шаблон:Nowrap.[5] Stable Jacobi ellipsoids with an axis ratio of Шаблон:Nowrap, as implied by its light-curve amplitude of Шаблон:Nowrap, exist for densities in the range of Шаблон:Nowrap.[5] The Johnston's Archive settles on Шаблон:Nowrap,[7] the centre of the latter range; for a Шаблон:Val equivalent spheroid body, this would equate to a mass of approximately Шаблон:Val. The extremely high estimated density (in contrast to any known similarly sized TNO)[8] would make it virtually certain that this object is a dwarf planet, but confirmation would require additional observation to refine the size and light curve details, preferably with discovery of a satellite to determine its mass.

In visible light, this object is neutral or slightly red in color and has a flat, featureless reflectance spectrum.[6]
