From Wikipedia, the free encyclopedia
2017 XO2, also written 2017 XO2, is a sub-kilometer asteroid and near-Earth object of the Apollo group approximately 110 meters (360 feet) in diameter. The asteroid was discovered by Pan-STARRS in December 2017,[1] after it already had approached Earth at 0.051 AU (7,600,000 km) or 20 lunar distances (LD) on 6 November 2017.[3] On 26 April 2057, it will pass Earth at a similar distance of 21 LD again.[3]
