2023 CY is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2023 CY 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 CY orbits the sun every 387 days (1.06 years), coming as close as 0.87 AU and reaching as far as 1.21 AU from the sun. Based on its brightness and the way it reflects light, 2023 CY is probably between 0.014 to 0.032 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2023 CY's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.
