Overview

443806 (1998 FL3) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1998 FL3 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

1998 FL3 orbits the sun every 517 days (1.42 years), coming as close as 0.95 AU and reaching as far as 1.57 AU from the sun. 1998 FL3 is about 0.3 kilometers in diameter, making it a small to average asteroid, comparable in size to a football field.

Close Approaches

1998 FL3's orbit is 0.04 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.

1998 FL3 has 6 close approaches predicted in the coming decades:
