(523719) 2014 LM28, provisional designation 2014 LM28, is a trans-Neptunian object and centaur, approximately 46 kilometers (29 miles) in diameter. It was discovered on 16 May 2013, by the Pan-STARRS 1 survey at Haleakala Observatory, Hawaii, United States.[1] The object’s orbit is highly inclined and very eccentric, with a perihelion closer to the Sun than Uranus and at an aphelion 17 times farther from the Sun than Neptune.

Orbit and classification

2014 LM28 orbits the Sun at a distance of 16.8–538.9 AU once every 4631 years and 1 month (1,691,491 days; semi-major axis of 277.83 AU). Its orbit has an eccentricity of 0.94 and an inclination of 85° with respect to the ecliptic.[2] The body’s observation arc begins with its official discovery observation by Pan-STARRS at Haleakala Observatory in May 2013.[1]

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 25 September 2018 (M.P.C. 111779).[4] As of 2018, it has not been named.[1]

Features

2014 LM28 has a highly inclined orbit typical of scattered objects and orbits nearly perpendicular to the ecliptic.
