    (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.
