Overview

162922 (2001 OY13) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2001 OY13 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2001 OY13 orbits the sun every 553 days (1.51 years), coming as close as 0.81 AU and reaching as far as 1.82 AU from the sun. Based on its brightness and the way it reflects light, 2001 OY13 is probably between 0.175 to 0.391 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2001 OY13's orbit is 0.01 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.

2001 OY13 has 13 close approaches predicted in the coming decades:
