Шаблон:Infobox planet

Шаблон:Mp, provisional designation Шаблон:Mp, is a trans-Neptunian object and binary system from the classical Kuiper belt, located in the outermost region of the Solar System. The cubewano belongs to the cold population and measures approximately Шаблон:Convert.[1] It was first observed on 10 December 2001, by astronomers at the Mauna Kea Observatory, Hawaii. Its 140-kilometer sized companion was discovered by the Hubble Space Telescope in June 2006.[2]

Discovery and orbit

Шаблон:Mp was discovered on 10 December 2001 by David C. Jewitt, Scott S. Sheppard and Jan Kleyna using 2.2-meter University of Hawaii reflector on Mauna Kea.[3] Шаблон:Mp belongs to the dynamically cold population of the classical Kuiper belt objects, which small orbital eccentricities and inclinations. Their semi-major axes reside mainly in the interval 40–45 AU.[1]

Satellite

Шаблон:Mp is a binary consisting of two components of approximately equal size. Assuming that both components have the same albedo, the primary is estimated to be about 170 km in diameter. The size of the secondary (satellite) in this case is estimated at about 140 km. The total mass of the system is about 4Шаблон:E kg. The average density of both components is about 1 g/cm3.[1]

Orbital parameters of the Шаблон:Mp system[4][5]
Semi-major axis (km) Eccentricity Period (d) Inclination (°)
9310 ± 49 0.5561 ± 0.0046 125.579 ± 0.049 41.07 ± 0.22

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 18 May 2019 (Шаблон:Small). As of 2019, it has not been named.[6]

Physical properties

The surfaces of both components of Шаблон:Mp appear to have a neutral color.[1]
