2014 OO6 (also written 2014 OO6) is the most dangerous near-Earth asteroid discovered in 2014 that remains on the Sentry Risk Table.[5] The asteroid is estimated to be roughly 75 meters (246 ft) in diameter and has a 1 in 83000 chance of impacting Earth on 11 January 2051.[3] But fortunately, 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 0.0297 AU (4,440,000 km; 2,760,000 mi) from Earth.[7] The asteroid has an observation arc of 24 days with an uncertainty parameter of 7.[2] The asteroid was last observed on 18 August 2014.[2] By 23 August 2014, the asteroid had dimmed to below magnitude 25.[8]
With an absolute magnitude of 23.1,[2] the asteroid is about 60–140 meters in diameter.[4]
