Шаблон:Infobox planet

Шаблон:Mp, provisional designation Шаблон:Mp, is a resonant trans-Neptunian object of the plutino group, located in the Kuiper belt in the outermost region of the Solar System. The rather bluish body measures approximately Шаблон:Convert in diameter.[1] It was discovered on 22 October 1998, by American astronomer Marc Buie at the Kitt Peak National Observatory in the United States.[2] It is probably not a dwarf planet candidate.[3]

Classification and orbit

Шаблон:Mp belongs to the plutino population,[1] which are named after the group's largest member, Pluto. Plutinos are resonant trans-Neptunian objects in 2:3 resonance with Neptune, orbiting the Sun twice for every three orbits Neptune does.

It orbits the Sun at a distance of 33.9–44.2 AU once every 244 years and 2 months (89,179 days; semi-major axis of 39.06 AU). Its orbit has an eccentricity of 0.13 and an inclination of 11° with respect to the ecliptic.[4] The body's observation arc begins with its official discovery observation. Its orbit still has a fair amount of uncertainty.[2]

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 28 October 2004 (Шаблон:Small).[5] As of 2018, it has not been named.[2]

Physical characteristics

Based on an absolute magnitude of 8.0 and an assumed albedo of 0.09, the Johnston's Archive estimates a diameter of 111 kilometers.[1] The body's spectrum (BB–BR) suggests a somewhat bluish color.[1] As of 2018, no rotational lightcurve of Шаблон:Mp has been obtained from photometric observations.[4][6] Шаблон:Mp it an unlikely dwarf planet candidate due to its small size, estimated by Michael Brown to measure 154 kilometers with a low albedo of 0.04.[3]
