Overview

2012 FR1 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2012 FR1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2012 FR1 orbits the sun every 1,170 days (3.20 years), coming as close as 0.63 AU and reaching as far as 3.73 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2012 FR1 is probably between 0.402 to 0.900 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2012 FR1's orbit is 0.01 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.

2012 FR1 has 8 close approaches predicted in the coming decades:
