Overview

2016 AF193 is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2016 AF193 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2016 AF193 orbits the sun every 299 days (0.82 years), coming as close as 0.62 AU and reaching as far as 1.13 AU from the sun. Based on its brightness and the way it reflects light, 2016 AF193 is probably between 0.730 to 3.240 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to Mount Everest.

Close Approaches

2016 AF193's orbit is 0.01 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 AF193 has 36 close approaches predicted in the coming decades:
