Overview
2007 FF1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 FF1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2007 FF1 orbits the sun every 685 days (1.88 years), coming as close as 0.79 AU and reaching as far as 2.25 AU from the sun. Based on its brightness and the way it reflects light, 2007 FF1 is probably between 0.113 to 0.252 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.
Close Approaches
2007 FF1'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.
2007 FF1 has 13 close approaches predicted in the coming decades:
