2014 DH is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2014 DH 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.
2014 DH orbits the sun every 358 days (0.98 years), coming as close as 0.63 AU and reaching as far as 1.34 AU from the sun. Based on its brightness and the way it reflects light, 2014 DH 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.
2014 DH'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.
2014 DH has 3 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| June 30, 2024 | 10,942,421 | 8.694 |
| June 28, 2025 | 6,557,302 | 12.056 |
| June 23, 2026 | 24,935,159 | 15.716 |
2014 DH's orbit is determined by observations dating back to Feb. 19, 2014. It was last officially observed on March 5, 2014. The IAU Minor Planet Center records 27 observations used to determine its orbit.
2014 DH can be reached with a journey of 450 days. This trajectory would require a delta-v of 9.605 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 4,723 potential trajectories and launch windows to this asteroid.
