2023 DA is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2023 DA 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.
2023 DA orbits the sun every 374 days (1.02 years), coming as close as 0.83 AU and reaching as far as 1.20 AU from the sun. Based on its brightness and the way it reflects light, 2023 DA is probably between 0.009 to 0.040 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2023 DA'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.

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) |
|---|---|---|
| March 10, 2116 | 0.00010 | 0.1343 |

2023 DA's orbit is determined by observations dating back to Feb. 16, 2023. It was last officially observed on Feb. 26, 2023. The IAU Minor Planet Center records 87 observations used to determine its orbit.
2023 DA can be reached with a journey of 386 days. This trajectory would require a delta-v of 5.619 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 808,503 potential trajectories and launch windows to this asteroid.
