(85640) 1998 OX4, also written 1998 OX4, is an Apollo asteroid and a Mars crosser. It was discovered on July 26, 1998, by the Spacewatch program and subsequently lost. It was re-discovered by the Near-Earth Asteroid Tracking (NEAT) project on August 31, 2002, as 2002 PJ34. It was removed from the Sentry Risk Table on 8 August 2002.[6] It has a well determined orbit with an observation arc of more than 10 years. It is included in the Minor Planet Center list of Potentially Hazardous Asteroids (PHAs) as it comes to within 0.05 AU of Earth periodically.
