Overview

490354 (2009 FF19) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2009 FF19 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2009 FF19 orbits the sun every 488 days (1.34 years), coming as close as 0.72 AU and reaching as far as 1.71 AU from the sun. Based on its brightness and the way it reflects light, 2009 FF19 is probably between 0.139 to 0.312 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2009 FF19'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.

2009 FF19 has 13 close approaches predicted in the coming decades:
