It was discovered on 24 June 1998, by the LINEAR survey at the Lincoln Laboratory's Experimental Test Site in Socorro, New Mexico.[3] Description{{mp|1998 ML|14}} 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. It is also a Mars-crossing asteroid.Shortly after its discovery, {{mp|1998 ML|14}} was imaged by radar at Goldstone and Arecibo.[1] 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.[10][11][12] On August 24, 2013 it passed at a distance of 21.9 Lunar distances. It was hoped to be observed by Goldstone radar.[2] Numbering and namingThis minor planet was numbered by the Minor Planet Center on 16 February 2003.[28] As of 2018, it has not been named.[3] References1. ^{{cite web|url=http://echo.jpl.nasa.gov/~lance/asteroid_radar_properties/nea.sc_oc.html|title=NEA CIRCULAR POLARIZATION RATIO RANKING|date=11 April 2006|accessdate=15 December 2009|publisher=Asteroid Radar Research}} [3][4][5][6][7][8][9][10]2. ^Goldstone radar 3. ^1 2 3 4 {{cite web |title = 52760 (1998 ML14) |work = Minor Planet Center |url = https://www.minorplanetcenter.net/db_search/show_object?object_id=52760 |accessdate = 23 October 2017}} 4. ^1 {{cite web |title = MPC/MPO/MPS Archive |work = Minor Planet Center |url = https://www.minorplanetcenter.net/iau/ECS/MPCArchive/MPCArchive_TBL.html |accessdate = 24 February 2018}} 5. ^1 2 3 4 {{cite web |title = LCDB Data for (52760) |publisher = Asteroid Lightcurve Database (LCDB) |url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=52760%7C |accessdate = 23 October 2017}} 6. ^1 {{Cite journal |display-authors = 6 |first1 = Steven J. |last1 = Ostro |first2 = R.
