Overview
417816 (2007 FA) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 FA as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2007 FA orbits the sun every 510 days (1.40 years), coming as close as 0.92 AU and reaching as far as 1.58 AU from the sun. Based on its brightness and the way it reflects light, 2007 FA is probably between 0.235 to 0.525 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
2007 FA'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.
2007 FA has 7 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
