2021 AV7 (original) (raw)
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 450–1,000 m (1,480–3,280 ft), it is considered a potentially hazardous asteroid. It has a highly elliptical orbit that brings it within Earth's orbit. Although its nominal orbit has a small minimum orbit intersection distance around 70,000 km (43,000 mi) from Earth's orbital path, the asteroid does not make any close approaches within 0.2 astronomical units (30×106 km; 19×106 mi) over the next 100 years.
