is a tiny near-Earth asteroid of the Apollo group, approximately 1sigfig=1NaNsigfig=1 in diameter. It was first observed by the Mount Lemmon Survey on 1 February 2020, when it passed Earth very closely at a nominal distance of only 0.000105AU. The object's orbital elements remain highly uncertain.
passed within 9730miles of the Earth on 1 February 2020, with a fly-by speed of 13.2miles per second. The household-appliance-sized asteroid passed within the orbit of satellites in the geostationary ring at 22300miles above Earth's equator. At the time, it was the closest approach in the year 2020. Since then, made a closer approach on 4 May 2020.
The asteroid was first observed 1 February 2020 by the Mount Lemmon Survey at Mount Lemmon Observatory in the Santa Catalina Mountains northeast of Tucson, Arizona. The next encounter closer than the Moon is predicted to occur 5 February 2029 at a distance of 11830miles or more.
