Overview

2013 GA80 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 GA80 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2013 GA80 orbits the sun every 464 days (1.27 years), coming as close as 0.99 AU and reaching as far as 1.35 AU from the sun. Based on its brightness and the way it reflects light, 2013 GA80 is probably between 0.133 to 0.298 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2013 GA80'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 GA80 has 10 close approaches predicted in the coming decades:
