It was first observed on 1 December 2008, by the Mount Lemmon Survey at Mount Lemmon Observatory in Arizona, United States. Orbit 2014 UR 116 orbits the Sun at a distance of 0.6–3.6 AU once every 3 years (1,088 days). Its orbit has an eccentricity of 0.73 and an inclination of 7° with respect to the ecliptic. Close approaches The asteroid has an Earth minimum orbital intersection distance of 0.0290 AU km on 3 which translates into 11.3 lunar distances. On 21 October 2014, it passed 0.0854 AU km mi on from Earth. On 10 April 2047, the asteroid will safely pass 0.0296 AU km mi on off from Earth. Although some inaccurate press reports have suggested that it may pose an impact risk to Earth, the NASA/JPL Near Earth Object Program Office reported that it poses no risk of impact to any planet for at least 150 years.http://www.nbcnews.com/science/space/nasa-says-asteroid-2014-ur116-nothing-be-afraid-n264281 NASA Says Asteroid 2014 UR116 Is Nothing to Be Afraid Of 9 December 2014 NBC News Between 1904 and 2174, the closest approach it makes to any planet was on 9 June 2008 when it passed 0.0144 AU km mi on from Mars. The asteroid has never been listed on the Sentry Risk Table and has a well determined orbit with an observation arc of 6 years. Discovery The asteroid was first detected on 1 December 2008 by the Mount Lemmon Survey and received the provisional designation 2008 XB. However, at an apparent magnitude of 20 and an assumed orbital eccentricity of 0.3, the object had a very short observation arc of less than 2 hours and the body became a lost minor planet. It was only recovered as 2014 UR 116 on 27 October 2014, by observers at the MASTER-II Observatory (C41) at Pulkovo Observatory in Kislovodsk, Russia.
