Overview

368565 (2004 FE5) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2004 FE5 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2004 FE5 orbits the sun every 508 days (1.39 years), coming as close as 0.50 AU and reaching as far as 1.99 AU from the sun. Based on its brightness and the way it reflects light, 2004 FE5 is probably between 0.255 to 0.570 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

2004 FE5's orbit is 0.03 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.

2004 FE5 has 10 close approaches predicted in the coming decades:
