Overview

2013 AS27 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 AS27 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2013 AS27 orbits the sun every 424 days (1.16 years), coming as close as 0.85 AU and reaching as far as 1.36 AU from the sun. Based on its brightness and the way it reflects light, 2013 AS27 is probably between 0.139 to 0.312 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2013 AS27'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 AS27 has 17 close approaches predicted in the coming decades:
