2020 CW is a tiny near-Earth asteroid of the Apollo group, approximately 1 meter (3 ft) in diameter. It was first observed by the Mount Lemmon Survey on 1 February 2020,[1] when it passed Earth very closely at a nominal distance of only 0.041 lunar distances (0.000105 astronomical units).[2] The object's orbital elements remain highly uncertain.[1][2]
