Overview
2013 WR67 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 WR67 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2013 WR67 orbits the sun every 1,490 days (4.08 years), coming as close as 0.72 AU and reaching as far as 4.38 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2013 WR67 is probably between 0.106 to 0.237 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.
Close Approaches
2013 WR67's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2013 WR67 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
