Overview

2013 AN20 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2013 AN20 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2013 AN20 orbits the sun every 647 days (1.77 years), coming as close as 1.02 AU and reaching as far as 1.91 AU from the sun. Based on its brightness and the way it reflects light, 2013 AN20 is probably between 0.116 to 0.259 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.

Close Approaches

2013 AN20's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

2013 AN20 has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Jan. 7, 2052 5,579,870 13.253
Jan. 9, 2091 10,503,618 13.427
Dec. 30, 2106 21,268,060 13.726
Jan. 7, 2146 5,710,963 13.255
Dec. 30, 2161 22,605,198 13.829
