Шаблон:Mp is a large trans-Neptunian object from the scattered disc located in the outermost region of the Solar System. It is one of the most distant objects from the Sun at 60.5 AU. The object is a dwarf planet candidate and measures approximately Шаблон:Convert in diameter. It was discovered on 19 September 2014, by American astronomer Scott Sheppard at the Cerro Tololo Observatory, Chile, and was provisionally designated Шаблон:Mp.[1]

Orbit and classification

This minor planet orbits the Sun at a distance of 35.0–88.4 AU once every 484 years and 10 months (177,075 days; semi-major axis of 61.71 AU). Its orbit has an eccentricity of 0.43 and an inclination of 18° with respect to the ecliptic.[2]

It is classified as a scattered disc object,[3] or "near-scattered" object in the classification of the Deep Ecliptic Survey,[4] that still gravitationally interacts with Neptune (30.1 AU) due to its relatively low perihelion of 35.0 AU, contrary to the extended-scattered/detached objects and sednoids which never approach Neptune as close.

Most distant objects from the Sun

Шаблон:Mp is moving closer to the Sun and will come to perihelion in 2106.[2] Шаблон:As of, it is at 60.5 AU from the Sun,[5] which makes it one of the most distant objects in the Solar System.[6]

Physical characteristics

Based on a generic magnitude-to-diameter conversion, Шаблон:Mp measures approximately Шаблон:Convert in diameter, for an assumed albedo of 0.9 and an magnitude of 5.1.[3][7] Mike Brown considers this object to be a likely dwarf planet candidate ("probably") estimating a mean-diameter of Шаблон:Convert.[8] Шаблон:As of, no rotational lightcurve for this object has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.[2]
