2018 CF2 is a micro-asteroid and near-Earth object of the Apollo group on an eccentric orbit with has an estimated 4–15 meters (10–50 ft). It was first observed on 7 February 2018, by astronomers of the Mount Lemmon Survey at Mount Lemmon Observatory, Arizona, United States.[1] The discovery occurred the day after its sub-lunar passage as it approached the Earth from a sunward direction, and this flyby altered the asteroid's orbit slightly.
