2014 OO6 (also written 2014 OO6) is an Apollo near-Earth asteroid discovered in 2014 and was the most dangerous one discovered in 2014 that remained on the Sentry Risk Table as of early December 2014.[5] The asteroid is estimated to be roughly 75 meters (246 ft) in diameter and had a 1 in 83,000 chance of impacting Earth on 11 January 2051.[5] However, the nominal best-fit orbit shows that 2014 OO6 will be 1.5 AU (220,000,000 km; 140,000,000 mi) from Earth on 11 January 2051.[6]
It was discovered on 27 July 2014 by Pan-STARRS at an apparent magnitude of 20 using a 1.8-meter (71 in) Ritchey–Chrétien telescope.[1] On 18 August 2014 the asteroid passed 0.02975 AU (4,451,000 km; 2,765,000 mi) from Earth.[7] By 23 August 2014, the asteroid had dimmed to below magnitude 25.[8] As of early December 2014, the asteroid had an observation arc of 24 days with an uncertainty parameter of 7.[2] 2014 OO6 was recovered by Cerro Paranal Observatory on 23 and 26 December 2014 at magnitude 25 which extended the observation arc from 24 days to 154 days.[9] The orbital refinement removed the impact risk for 11 January 2051.[3]
With an absolute magnitude of 23.1,[2] the asteroid is about 60–140 meters in diameter.[4]
