Overview

2013 JN7 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 JN7 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2013 JN7 orbits the sun every 823 days (2.25 years), coming as close as 0.62 AU and reaching as far as 2.82 AU from the sun. Based on its brightness and the way it reflects light, 2013 JN7 is probably between 0.168 to 0.375 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2013 JN7's orbit is 0.04 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 JN7 has 14 close approaches predicted in the coming decades:
