2018 FK5 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 FK5 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.
2018 FK5 orbits the sun every 418 days (1.14 years), coming as close as 0.77 AU and reaching as far as 1.42 AU from the sun. Based on its brightness and the way it reflects light, 2018 FK5 is probably between 0.006 to 0.013 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2018 FK5'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.
2018 FK5 has 3 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Oct. 1, 2019 | 5,093,446 | 10.476 |
| April 1, 2026 | 7,890,053 | 10.030 |
| Oct. 4, 2027 | 1,714,690 | 11.594 |
NASA Sentry has assessed impact risk for 2 very close approach scenarios. Here are the top scenarios ordered by probability of impact:
| Date | Probability of Impact (%) | Impact Energy (Mt) |
|---|---|---|
| Oct. 3, 2110 | 0.00022 | 0.01747 |
| Oct. 3, 2087 | 0.00015 | 0.01749 |
2018 FK5's orbit is determined by observations dating back to March 28, 2018. It was last officially observed on March 29, 2018. The IAU Minor Planet Center records 33 observations used to determine its orbit.
