Overview

86819 (2000 GK137) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 GK137 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2000 GK137 orbits the sun every 1,030 days (2.82 years), coming as close as 0.99 AU and reaching as far as 3.01 AU from the sun. 2000 GK137 is about 0.8 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

The rotation of 2000 GK137 has been observed. It completes a rotation on its axis every 3.02 hours.

2000 GK137's spectral type None (Tholen) / Sq (SMASSII) indicates that it is likely to contain and .
