2018 BF3 is a micro-asteroid, classified as a near-Earth object of the Apollo group, approximately 20 meters (70 ft) in diameter. It was first observed on 20 January 2018, by astronomers of the Catalina Sky Survey at Mount Lemmon Observatory in Arizona, United States,[1] the day after the closest flyby, due to its approach from the direction of the Sun.
