Overview
2010 CB19 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 CB19 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.
2010 CB19 orbits the sun every 380 days (1.04 years), coming as close as 0.71 AU and reaching as far as 1.34 AU from the sun. Based on its brightness and the way it reflects light, 2010 CB19 is probably between 0.022 to 0.098 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2010 CB19'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.
2010 CB19 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| July 8, 2030 | 23,982,571 | 13.982 |
| July 22, 2031 | 15,116,895 | 7.243 |
| Feb. 6, 2036 | 6,941,656 | 8.412 |
| Feb. 15, 2037 | 29,558,292 | 15.521 |
| July 12, 2057 | 12,320,361 | 11.482 |
| Feb. 7, 2063 | 485,425 | 9.821 |
Images and Observations
2010 CB19's orbit is determined by observations dating back to Feb. 13, 2010. It was last officially observed on March 4, 2010. The IAU Minor Planet Center records 36 observations used to determine its orbit.
Accessibility and Exploration
2010 CB19 can be reached with a journey of 394 days. This trajectory would require a delta-v of 11.065 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 518 potential trajectories and launch windows to this asteroid.
