Overview

2013 QC11 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 QC11 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2013 QC11 orbits the sun every 679 days (1.86 years), coming as close as 0.58 AU and reaching as far as 2.45 AU from the sun. Based on its brightness and the way it reflects light, 2013 QC11 is probably between 0.128 to 0.287 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.

Close Approaches

2013 QC11'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.

2013 QC11 has 10 close approaches predicted in the coming decades:
