2020 CD3 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 CD3 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.
2020 CD3 orbits the sun every 379 days (1.04 years), coming as close as 0.99 AU and reaching as far as 1.06 AU from the sun. Based on its brightness and the way it reflects light, 2020 CD3 is probably between 0.001 to 0.004 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2020 CD3'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.

2020 CD3's orbit is determined by observations dating back to Feb. 15, 2020. It was last officially observed on March 22, 2020. The IAU Minor Planet Center records 60 observations used to determine its orbit.
2020 CD3 can be reached with a journey of 378 days. This trajectory would require a delta-v of 3.571 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 2,239,827 potential trajectories and launch windows to this asteroid.
