2011 CQ1 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2011 CQ1 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.
2011 CQ1 orbits the sun every 279 days (0.76 years), coming as close as 0.66 AU and reaching as far as 1.01 AU from the sun. Based on its brightness and the way it reflects light, 2011 CQ1 is probably between 0.001 to 0.003 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2011 CQ1'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.
2011 CQ1 has 11 close approaches predicted in the coming decades:

2011 CQ1's orbit is determined by observations dating back to Feb. 4, 2011. It was last officially observed on Feb. 4, 2011. The IAU Minor Planet Center records 35 observations used to determine its orbit.
2011 CQ1 can be reached with a journey of 178 days. This trajectory would require a delta-v of 8.904 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 21,587 potential trajectories and launch windows to this asteroid.
