2021 CD6 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2021 CD6 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2021 CD6 orbits the sun every 1,210 days (3.31 years), coming as close as 0.99 AU and reaching as far as 3.47 AU from the sun. Based on its brightness and the way it reflects light, 2021 CD6 is probably between 0.228 to 0.511 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
2021 CD6's orbit is 0.01 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.
2021 CD6 has 5 close approaches predicted in the coming decades:
Date | Distance from Earth (km) | Velocity (km/s) |
---|---|---|
Oct. 30, 2050 | 19,111,422 | 11.564 |
Oct. 15, 2060 | 6,389,252 | 11.783 |
Oct. 25, 2070 | 14,790,487 | 11.472 |
Nov. 8, 2080 | 26,517,135 | 12.005 |
Oct. 4, 2197 | 8,987,184 | 13.080 |
2021 CD6's orbit is determined by observations dating back to Nov. 8, 2020. It was last officially observed on June 11, 2023. The IAU Minor Planet Center records 52 observations used to determine its orbit.
