, provisional designation , is a bright, sub-kilometer asteroid, classified as near-Earth object and potentially hazardous asteroid of the Apollo asteroid, Apollo group. Based on Absolute magnitude#Solar System bodies (H), absolute magnitude, it is the second largest asteroid known to have passed closer than the Moon.

Description

was discovered on 7 February 2002 by Lincoln Near-Earth Asteroid Research (LINEAR) at an apparent magnitude of 19 using a reflecting telescope. It has an estimated diameter of . The asteroid was listed on Sentry (monitoring system), Sentry Risk Table with a Torino Scale rating of 1 on 20 March 2002. With an observation arc of 44 days, showed a 1 in 9,300 chance of Impact event, 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 from Earth. Even though using an Epoch (astronomy), epoch of 27 June 2015 gives an Earth-Minimum orbit intersection distance, MOID of , the asteroid does not make any threatening approaches to Earth in the foreseeable future. The close approach of 2080 will cause an uncertainty of 4 minutes for the close approach time of 2084.
