2004 BX159 (also written 2004 BX159) is an object which was thought to be a Mars-crossing asteroid because of the poorly known orbit after discovery, and was therefore listed on the Sentry Risk Table as a possible impactor.[3] With an observation arc of 3 days, perihelion was determined to be 1.5 ± 3 AU.[4]
Precovery observations in archival data of the Canada-France-Hawaii Telescope on Mauna Kea were identified in early 2014, resulting in a dramatic improvement of the orbital accuracy, sufficient to recognize the object as a regular main belt asteroid, not posing any danger to Earth.[1]
The object was subsequently linked by the Minor Planet Center with additional observations reported since 1997, and it now has a well-established orbit with a 16-year observed arc.[1]
