(52760) 1998 ML14, provisional designation 1998 ML14, is a stony asteroid, classified as near-Earth object of the Apollo group and potentially hazardous asteroid, approximately 1 kilometer in diameter. It was discovered on 24 June 1998, by the LINEAR survey at the Lincoln Laboratory's Experimental Test Site in Socorro, New Mexico. [2]
1998 ML14 orbits the Sun at a distance of 0.9–3.9 AU once every 3 years and 9 months (1,366 days). Its orbit has an eccentricity of 0.62 and an inclination of 2° with respect to the ecliptic. [1] It is also a Mars-crossing asteroid.
Shortly after its discovery, 1998 ML14 was imaged by radar at Goldstone and Arecibo. [9]
The study showed that the asteroid has a rotation period of 15 hours, and a shape that is roughly spherical, with some steep protrusions and large craters. [6] [7] [8]
On 24 August 2013 it passed at a distance of 21.9 Lunar distances. [1] It was hoped to be observed by Goldstone radar. [10]
This minor planet was numbered by the Minor Planet Center on 16 February 2003. [11] As of 2018, it has not been named. [2]

On 27 May 2022, the asteroid made a close approach 0.027 astronomical units from Earth. During the close approach, optical observations detected signs of an orbiting satellite, which was later confirmed by radar imaging at NASA's Goldstone Solar System Radar in California.
