(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]

Description

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]

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 16 February 2003. [11] As of 2018, it has not been named. [2]
