Based on absolute magnitude, it is the second largest asteroid known to have passed closer than the Moon. Description 2002 CU 11 was discovered on 7 February 2002 by Lincoln Near-Earth Asteroid Research (LINEAR) at an apparent magnitude of 19 using a 1.0 m in on us reflecting telescope. It has an estimated diameter of 730 m us. The asteroid was listed on Sentry Risk Table with a Torino Scale rating of 1 on 20 March 2002. With an observation arc of 44 days, (163132) 2002 CU 11 showed a 1 in 9,300 chance of impacting Earth in 2049. It was removed from the Sentry Risk Table on 26 April 2002. It is now known that on 3 September 2049 the asteroid will be 0.0843 AU km mi on on from Earth. Even though using an epoch of 27 June 2015 gives 2002 CU 11 an Earth-MOID of 0.0000093 AU km mi on off, the asteroid does not make any threatening approaches to Earth in the foreseeable future. +Notable close-approaches to Earth Date Distance from Earth 1925-08-30 0.0023 AU km mi on on 2014-08-30 0.0346 AU km mi on off 2049-09-03 0.0843 AU km mi on off 2080-08-31 0.0042 AU km mi on off The close approach of 2080 will cause an uncertainty of 4 minutes for the close approach time of 2084.
