Overview

2013 XA22 is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 XA22 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2013 XA22 orbits the sun every 422 days (1.16 years), coming as close as 0.84 AU and reaching as far as 1.36 AU from the sun. Based on its brightness and the way it reflects light, 2013 XA22 is probably between 0.480 to 2.140 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.

Close Approaches

2013 XA22'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 XA22 has 28 close approaches predicted in the coming decades:
