(163132) 2002 CU11, provisionally known as 2002 CU11, is a near-Earth asteroid and potentially hazardous object.[2] It was discovered on 7 February 2002 by Lincoln Near-Earth Asteroid Research (LINEAR) at an apparent magnitude of 19 using a 1.0-meter (39 in) reflecting telescope.[1] It has an estimated diameter of 730 meters (2,400 ft).[3] The asteroid was listed on Sentry Risk Table with a Torino Scale rating of 1 on 20 March 2002.[3]
With an observation arc of 44 days, (163132) 2002 CU11 showed a 1 in 9,300 chance of impacting Earth in 2049.[4] It was removed from the Sentry Risk Table on 26 April 2002.[5] It is now known that on 3 September 2049 the asteroid will be 0.0843 AU (12,610,000 km; 7,840,000 mi) from Earth.[6]
Even though using an epoch of 27 June 2015 gives 2002 CU11 an Earth-MOID of 0.0000093 AU (1,390 km; 860 mi),[2] the asteroid does not make any threatening approaches to Earth in the foreseeable future.
