Overview

2017 JF3 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2017 JF3 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2017 JF3 orbits the sun every 315 days (0.86 years), coming as close as 0.59 AU and reaching as far as 1.22 AU from the sun. Based on its brightness and the way it reflects light, 2017 JF3 is probably between 0.078 to 0.349 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2017 JF3'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.

2017 JF3 has 28 close approaches predicted in the coming decades:
