2015 FF is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2015 FF 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.
2015 FF orbits the sun every 519 days (1.42 years), coming as close as 0.84 AU and reaching as far as 1.69 AU from the sun. Based on its brightness and the way it reflects light, 2015 FF is probably between 0.008 to 0.037 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2015 FF'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.
2015 FF has 2 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Aug. 12, 2022 | 4,283,841 | 9.166 |
| Aug. 19, 2066 | 12,284,783 | 11.739 |
2015 FF's orbit is determined by observations dating back to March 16, 2015. It was last officially observed on March 20, 2015. The IAU Minor Planet Center records 23 observations used to determine its orbit.
2015 FF can be reached with a journey of 362 days. This trajectory would require a delta-v of 10.05 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 2,291 potential trajectories and launch windows to this asteroid.
