Шаблон:Mp is an extreme trans-Neptunian object from the scattered disc, located in the outermost regions of the Solar System, approximately Шаблон:Convert in diameter. It was discovered on 2 August 2013, by astronomers of the Outer Solar System Origins Survey at Mauna Kea Observatory, Hawaii, United States.[1]

Orbit

With a semi-major axis of 196 AU, Шаблон:Mp orbits the Sun at a distance of 43.9–348 AU once every 2,742 years. Its orbit has an eccentricity of 0.78 and an inclination of 11° with respect to the ecliptic.[2] It has a similar orbit to Шаблон:Mpl, except for a smaller inclination.

Шаблон:Mp belongs to a small number of detached objects with perihelion distances of 30 AU or more, and semi-major axes of 150 AU or more.[3] Such objects can not reach such orbits without some perturbing object, which lead to the speculation of planet nine.

Physical characteristics

Spectral type

The object is estimated to have a bluish spectra (BB).[4]

Diameter

Шаблон:Mp has been estimated to measure 243 and 340 kilometers in diameter, based on an assumed albedo of 0.09 and 0.04, respectively.[5][4] A generic magnitude-to-diameter conversion gives a mean-diameter of 260 kilometers,[6] using with a typical albedo of 0.08 and a published absolute magnitude of 6.2951.[2]

Numbering and naming

Шаблон:Mp was numbered (505478) by the Minor Planet Center on 4 November 2017 (Шаблон:Small).[7] As of 2017, this minor planet has not received a name.[1]
