Overview

2016 XA2 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2016 XA2 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2016 XA2 orbits the sun every 1,077 days (2.95 years), coming as close as 0.51 AU and reaching as far as 3.60 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2016 XA2 is probably between 0.127 to 0.284 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
