2018 CC is a micro-asteroid, classified as a near-Earth object of the Apollo group, approximately 20 meters (70 ft) in diameter. Its official first observation was made by the Catalina Sky Survey at Mount Lemmon Observatory, Arizona, United States, on 4 February 2018.[1] Two days later, the asteroid crossed the orbit of the Moon and made a very close approach to Earth.[2]
