Overview
2023 CM is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2023 CM as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2023 CM orbits the sun every 1,200 days (3.29 years), coming as close as 0.85 AU and reaching as far as 3.57 AU from the sun. Based on its brightness and the way it reflects light, 2023 CM is probably between 0.134 to 0.301 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
Close Approaches
2023 CM'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.
2023 CM has 1 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| March 14, 2023 | 3,942,964 | 14.027 |
Images and Observations
2023 CM's orbit is determined by observations dating back to Feb. 2, 2023. It was last officially observed on March 13, 2023. The IAU Minor Planet Center records 261 observations used to determine its orbit.
