Overview

410777 (2009 FD) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2009 FD as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2009 FD orbits the sun every 459 days (1.26 years), coming as close as 0.59 AU and reaching as far as 1.74 AU from the sun. 2009 FD is about 0.5 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, comparable in size to the U.S. Capitol building.

The rotation of 2009 FD has been observed. It completes a rotation on its axis every 4.00 hours.

Close Approaches

2009 FD'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 FD has 20 close approaches predicted in the coming decades:
