Overview
2014 JN57 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2014 JN57 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2014 JN57 orbits the sun every 506 days (1.39 years), coming as close as 1.03 AU and reaching as far as 1.45 AU from the sun. 2014 JN57 is about 0.3 kilometers in diameter, making it a small to average asteroid, comparable in size to a football field.
Close Approaches
2014 JN57's orbit is 0.05 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.
2014 JN57 has 9 close approaches predicted in the coming decades:
