Overview
2016 PF8 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2016 PF8 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2016 PF8 orbits the sun every 439 days (1.20 years), coming as close as 0.49 AU and reaching as far as 1.77 AU from the sun. Based on its brightness and the way it reflects light, 2016 PF8 is probably between 0.138 to 0.308 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
Close Approaches
2016 PF8's orbit is 0.02 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.
2016 PF8 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| July 22, 2022 | 15,916,473 | 15.046 |
| July 23, 2028 | 13,229,338 | 15.587 |
| July 23, 2034 | 12,843,773 | 15.668 |
| July 22, 2040 | 15,198,752 | 15.195 |
| July 22, 2046 | 18,793,402 | 14.493 |
| July 20, 2052 | 23,898,117 | 13.532 |
