Overview
2012 XA133 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2012 XA133 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2012 XA133 orbits the sun every 559 days (1.53 years), coming as close as 0.40 AU and reaching as far as 2.25 AU from the sun. Based on its brightness and the way it reflects light, 2012 XA133 is probably between 0.171 to 0.382 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
The rotation of 2012 XA133 has been observed. It completes a rotation on its axis every 3.28 hours.
Close Approaches
2012 XA133's orbit is 0.02 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.
2012 XA133 has 15 close approaches predicted in the coming decades:
