Overview

2013 QR1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 QR1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2013 QR1 orbits the sun every 995 days (2.72 years), coming as close as 0.51 AU and reaching as far as 3.39 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2013 QR1 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 basketball court.

The rotation of 2013 QR1 has been observed. It completes a rotation on its axis every 0.09 hours.

Close Approaches

2013 QR1'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 QR1 has 8 close approaches predicted in the coming decades:
