Overview
2016 JN is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2016 JN as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
2016 JN orbits the sun every 723 days (1.98 years), coming as close as 1.03 AU and reaching as far as 2.12 AU from the sun. Based on its brightness and the way it reflects light, 2016 JN is probably between 0.056 to 0.124 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2016 JN's orbit is 0.11 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
2016 JN has 9 close approaches predicted in the coming decades:
