2020 CW is an asteroid classified as a Near-Earth Object (NEO) that passed within 9,730 miles (15,660 km) of the Earth on February 1, 2020, with a fly-by speed of 13.2 miles (21.2 km) per second.[3] The household-appliance-sized asteroid passed within the orbit of satellites in the geostationary ring at 22,300 miles (35,900 km) above Earth's equator.[1] At the time, it was the closest approach in the year 2020. Since then, 2020 JJ made a closer approach on May 4, 2020.[5]
The asteroid was discovered February 1, 2020 using the Mount Lemmon Survey telescope in the Santa Catalina Mountains northeast of Tucson, Arizona.[2] The next encounter closer than the Moon is predicted to occur February 5, 2029 at a distance of 11,830 miles (19,040 km) or more.[3]
