2018 DV1 is a micro-asteroid, classified as a near-Earth object of the Aten group, approximately 6–12 meters (20–40 feet) in diameter. It was first observed on 26 February 2018, by astronomers of the Mount Lemmon Survey at Mount Lemmon Observatory, Arizona, five days prior to its sub-lunar close encounter with Earth at less than 0.3 lunar distance.[1]
