Шаблон:Infobox planet

Шаблон:Mp, provisional designation Шаблон:Mp, is a resonant trans-Neptunian object in the outermost region of the Solar System, guesstimated at approximately Шаблон:Convert in diameter. It was discovered on 13 March 2010, by astronomers with the Pan-STARRS survey at Haleakala Observatory, Hawaii, United States.[1]

Discovery

The body's observation arc begins with a precovery taken by the Sloan Digital Sky Survey in April 2000, nearly 10 years prior to its official discovery observation at Haleakala Observatory.[1] The discovery was announced in a Minor Planet Electronic Circular in July 2016, after additional observations by Pan-STARRS had been found (2010–2013), preceding the team's original observation from 11 January 2015, which led to the assignment of the object's first and only provisional designation, Шаблон:Mp.[2] The observations were made with Pan-STARRS 1.8-meter Ritchey–Chrétien telescope, and B. Gibson, T. Goggia, N. Primak, A. Schultz, and M. Willman were the observers.[2]

Orbit and classification

Шаблон:Mp is a resonant trans-Neptunian object in a 2:5 orbital resonance with Neptune, which means that it orbits the Sun exactly twice while Neptune orbits the Sun five times.[3] Several objects in this resonance with a period of 410 years have been found, including Шаблон:Mpl-.

It orbits the Sun at a distance of 41.4–68.9 AU once every 409 years and 5 months (149,540 days; semi-major axis of 55.14 AU). Its orbit has an eccentricity of 0.25 and an inclination of 27° with respect to the ecliptic.[4] It still has an orbital uncertainty of 1 and 3, respectively.[1][4]

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 9 June 2017 and received the number Шаблон:LoMP in the minor planet catalog (Шаблон:Small).[5] 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 468 and 479 kilometers in diameter based on an assumed albedo of 0.09 and 0.07, respectively.[3][6] As of 2018, no rotational lightcurve has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.[4][7]
