2019 OK[a] is a near-Earth asteroid noted for its sudden, surprise discovery on the day before it flew by at approximately 70,000 km (43,000 mi) in 2019.[4] The object's size is estimated at 57 to 130 metres (187 to 426 ft) across, the closest asteroid of such size discovered in 2019.[5] It is uncommon for asteroids of this moderately large size to pass within 100,000 km (62,000 mi) of Earth.
