2004 BX159, also written 2004 BX159, is an estimated 1.2-kilometer-sized body of the Solar System. It was thought to be a Mars-crossing asteroid because of its 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 astronomical units (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 body was subsequently linked by the Minor Planet Center with additional observations reported since 1997. It has now a well-established orbit, observed over decades, with the lowest possible uncertainty of 0.[1]
