Overview

2017 WV13 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 WV13 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2017 WV13 orbits the sun every 534 days (1.46 years), coming as close as 0.42 AU and reaching as far as 2.16 AU from the sun. Based on its brightness and the way it reflects light, 2017 WV13 is probably between 0.153 to 0.342 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2017 WV13's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2017 WV13 has 13 close approaches predicted in the coming decades:
