Overview
152667 (1998 FR11) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1998 FR11 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.
1998 FR11 orbits the sun every 1,720 days (4.71 years), coming as close as 0.82 AU and reaching as far as 4.79 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 1998 FR11 is probably between 1.382 to 3.091 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.
Close Approaches
1998 FR11's orbit is 0.06 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.
1998 FR11 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
