Overview
2023 CD is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2023 CD 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 CD orbits the sun every 355 days (0.97 years), coming as close as 0.87 AU and reaching as far as 1.10 AU from the sun. Based on its brightness and the way it reflects light, 2023 CD is probably between 0.027 to 0.120 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2023 CD's orbit is 0.09 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.
2023 CD has 41 close approaches predicted in the coming decades:

Images and Observations
2023 CD's orbit is determined by observations dating back to Feb. 1, 2023. It was last officially observed on March 16, 2023. The IAU Minor Planet Center records 73 observations used to determine its orbit.
Accessibility and Exploration
2023 CD can be reached with a journey of 362 days. This trajectory would require a delta-v of 8.738 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 59,751 potential trajectories and launch windows to this asteroid.
