2016 DV1 is a near-Earth asteroid estimated to be roughly 29–65 meters (95–210 feet) in diameter. It is a fast rotating asteroid of the Apollo group which was first observed by the Mount Lemmon Survey on 28 February 2016, just days before it passed Earth at 1 lunar distance (LD) on 3 March 2016. The elongated fast rotator has a rotation period of 303 seconds. It was recovered in February 2021 as it was about to pass Earth on 3 March 2021 at a distance of 0.0053 AU (2.1 LD; 790,000 km; 490,000 mi).[3]
