2017 DK34 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 DK34 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.
2017 DK34 orbits the sun every 490 days (1.34 years), coming as close as 0.83 AU and reaching as far as 1.61 AU from the sun. Based on its brightness and the way it reflects light, 2017 DK34 is probably between 0.008 to 0.034 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2017 DK34'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.
2017 DK34 has 2 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Feb. 24, 2021 | 24,297,240 | 13.548 |
| Dec. 16, 2063 | 25,421,142 | 7.357 |
2017 DK34's orbit is determined by observations dating back to Feb. 17, 2017. It was last officially observed on Feb. 25, 2017. The IAU Minor Planet Center records 42 observations used to determine its orbit.
2017 DK34 can be reached with a journey of 402 days. This trajectory would require a delta-v of 11.229 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 70 potential trajectories and launch windows to this asteroid.
