Overview

67381 (2000 OL8) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 OL8 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2000 OL8 orbits the sun every 554 days (1.52 years), coming as close as 0.60 AU and reaching as far as 2.04 AU from the sun. Based on its brightness and the way it reflects light, 2000 OL8 is probably between 0.290 to 0.649 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

2000 OL8's orbit is 0.02 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.

2000 OL8 has 16 close approaches predicted in the coming decades:
