Шаблон:Infobox planet

Шаблон:Mp, provisional designation Шаблон:Mp, is a trans-Neptunian object on an eccentric orbit from the scattered disc, located in the outermost region of the Solar System. It was discovered on 20 May 2012, by astronomers with the Pan-STARRS survey at Haleakala Observatory, Hawaii, United States.[1] The dwarf planet candidate measures approximately Шаблон:Convert in diameter.

Orbit and classification

Шаблон:Mp is a scattered disc object and orbits the Sun at a distance of 35.5–88.0 AU once every 485 years and 4 months (177,277 days; semi-major axis of 61.76 AU). Its orbit has an eccentricity of 0.43 and an inclination of 10° with respect to the ecliptic.[2]

The body's observation arc begins with a precovery taken by Pan-STARRS in May 2010, two years prior to its official discovery observation.[1] It still has a small orbital uncertainty of 1 and 2, respectively.[1][2]

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 25 September 2018 and received the number Шаблон:LoMP in the minor planet catalog (Шаблон:Small).[3] As of 2018, it has not been named.[1]

Physical characteristics

According to the Johnston's archive and American astronomer Michael Brown, Шаблон:Mp measures 293 and 302 kilometers in diameter based on an assumed albedo of 0.09 and 0.08, respectively.[4][5] On his website, Michael Brown lists this object as a "possible" dwarf planet (200–400 km) which is the category with the lowest certainty in his 5-class taxonomic system.[5] As of 2018, no spectral type and color indices, nor a rotational lightcurve have been obtained from spectroscopic and photometric observations. The body's color, rotation period, pole and shape remain unknown.[2][6]
