(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 astronomical unit|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]
