2008 CD70 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2008 CD70 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.
2008 CD70 orbits the sun every 409 days (1.12 years), coming as close as 0.99 AU and reaching as far as 1.17 AU from the sun. Based on its brightness and the way it reflects light, 2008 CD70 is probably between 0.006 to 0.028 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2008 CD70's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2008 CD70 has 7 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Aug. 31, 2026 | 22,735,025 | 6.787 |
| Feb. 15, 2027 | 17,949,085 | 8.031 |

| Feb. 13, 2094 | 11,433,522 | 7.383 |
2008 CD70's orbit is determined by observations dating back to Feb. 9, 2008. It was last officially observed on Feb. 13, 2008. The IAU Minor Planet Center records 64 observations used to determine its orbit.
2008 CD70 can be reached with a journey of 362 days. This trajectory would require a delta-v of 8.606 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 6,977 potential trajectories and launch windows to this asteroid.
