Overview
2010 CD55 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 CD55 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 CD55 orbits the sun every 378 days (1.03 years), coming as close as 0.82 AU and reaching as far as 1.23 AU from the sun. 2010 CD55 is about 0.1 kilometers in diameter, making it a small to average asteroid, comparable in size to a school bus or smaller.
Close Approaches
2010 CD55'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.
2010 CD55 has 29 close approaches predicted in the coming decades:
