Overview

2016 OF is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2016 OF 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 OF orbits the sun every 545 days (1.49 years), coming as close as 0.99 AU and reaching as far as 1.62 AU from the sun. Based on its brightness and the way it reflects light, 2016 OF is probably between 0.061 to 0.136 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2016 OF's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2016 OF has 10 close approaches predicted in the coming decades:
