(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]
