Overview

2014 WE365 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 WE365 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2014 WE365 orbits the sun every 499 days (1.37 years), coming as close as 0.61 AU and reaching as far as 1.85 AU from the sun. Based on its brightness and the way it reflects light, 2014 WE365 is probably between 0.154 to 0.345 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2014 WE365's orbit is 0.03 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.

2014 WE365 has 17 close approaches predicted in the coming decades:
