Overview

2014 FO47 is a very small asteroid with an orbit that is entirely confined within Earth's orbit. NASA JPL has classified 2014 FO47 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2014 FO47 orbits the sun every 238 days (0.65 years), coming as close as 0.55 AU and reaching as far as 0.96 AU from the sun. Based on its brightness and the way it reflects light, 2014 FO47 is probably between 0.233 to 0.520 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to a football field.

Close Approaches

2014 FO47'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 FO47 has 24 close approaches predicted in the coming decades:
