Overview

159504 (2000 WO67) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 WO67 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2000 WO67 orbits the sun every 1,390 days (3.81 years), coming as close as 0.93 AU and reaching as far as 3.94 AU from the sun. 2000 WO67 is about 2.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

The rotation of 2000 WO67 has been observed. It completes a rotation on its axis every 7.84 hours.
