, provisional designation, is a bright, sub-kilometer asteroid, classified as near-Earth object and potentially hazardous asteroid of the Apollo group. Based on absolute magnitude, it is the second largest asteroid known to have passed closer than the Moon.
was discovered on 7 February 2002 by Lincoln Near-Earth Asteroid Research (LINEAR) at an apparent magnitude of 19 using a 1adj=onNaNadj=on reflecting telescope. It has an estimated diameter of 730m (2,400feet). 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, 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 0.0843abbr=onNaNabbr=on from Earth.
Even though using an epoch of 27 June 2015 gives an Earth-MOID of 9.3E-06abbr=onNaNabbr=on, 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.
