It was discovered on 18 June 2012 by astronomers of the Catalina Sky Survey at an apparent magnitude of 19.9 using a 0.68 m in on us Schmidt–Cassegrain telescope. It has an estimated diameter of 240 m us. The asteroid was listed on Sentry Risk Table with a Torino Scale rating of 1 on 23 June 2012. Orbit and classification 2012 MU 2 is a member of the Apollo asteroids, a group of near-Earth objects with an Earth-crossing orbit. It orbits the Sun at a distance of 1.0–3.1 AU once every 2 years and 11 months (1,076 days; semi-major axis of 2.06 AU). Its orbit has an eccentricity of 0.51 and an inclination of 11° with respect to the ecliptic. On 24 June 2012 with an observation arc of 6 days, 2012 MU 2 showed a 1 in 7,140 chance of impacting Earth on 1 June 2015. It was removed from the Sentry Risk Table on the next day (25 June). With an observation arc of 113 days, the JPL Small-Body Database (solution JPL 42 dated 2013-Aug-05) shows that 2012 MU 2 may make a very close approach to asteroid 29 Amphitrite on 8 April 2179. The minimum approach distance is about 0.000032 AU km mi on on, but the maximum distance is 0.14 AU km mi on off. The nominal approach is 0.047 AU km mi on off. The Earth approach in 2015 occurred on 15 May 2015 at a distance of 0.11485 AU km mi on off. Numbering and naming This minor planet was numbered by the Minor Planet Center on 25 September 2018 (M.P.C. 111778). As of 2018, it has not been named. References 30em 2018-09-12 last obs.
