2021 AV7 is a near-Earth asteroid of the Apollo group, discovered by astronomers Alain Maury and G. Attard at San Pedro de Atacama, Chile on 15 January 2021. With an estimated diameter of 440–1,000 m (1,440–3,280 ft), it is considered a potentially hazardous asteroid. It has a highly elliptical orbit that brings it within Earth's orbit. However, its nominal orbit has a minimum orbit intersection distance around 2.6×10^6 km (1.6×10^6 mi) from Earth's orbital path, and the closest approach the asteroid is expected to make over the next two centuries is to within 0.140 astronomical units (20.9×10^6 km; 13.0×10^6 mi) on 28 February 2096.[4]
