    (163364) 2002 OD20 is an asteroid, classified as a near-Earth object and potentially hazardous asteroid of the Apollo group, likely smaller than one kilometer in diameter. [1] [3]

    It was scheduled to be observed by Goldstone radar in May 2013. [4] It has a well determined orbit and made a close approach to Earth on 23 May 2013, at a distance of 0.0387  AU (5,790,000  km ; 3,600,000  mi ). [1] [4] It is due to make another close pass on 23 May 2131, coming as close as 0.0248 AU. [1] It was discovered on 21 July 2002 by astronomers of the Near-Earth Asteroid Tracking survey at Palomar Observatory in California. [5] With an absolute magnitude of 18.8, [1] the diameter is estimated to between 460 and 1030 meters. [2]
