1991 VG is a very small near-Earth object of the Apollo group, approximately 5–12 meters (16–39 feet) in diameter. It was first observed by American astronomer James Scotti on 6 November 1991, using the Spacewatch telescope on Kitt Peak National Observatory near Tucson, Arizona, in the United States.[1][4] On 6 December 1991 it passed about 369635 km from the Moon.[2] The asteroid then went unobserved from April 1992 until it was recovered by Paranal Observatory in May 2017.[1] It was removed from the Sentry Risk Table on 1 June 2017.[5]
