Overview

465824 (2010 FR) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 FR as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2010 FR orbits the sun every 440 days (1.20 years), coming as close as 0.72 AU and reaching as far as 1.55 AU from the sun. Based on its brightness and the way it reflects light, 2010 FR is probably between 0.121 to 0.272 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2010 FR's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2010 FR has 18 close approaches predicted in the coming decades:
