Overview

2020 CQ2 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2020 CQ2 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.

2020 CQ2 orbits the sun every 340 days (0.93 years), coming as close as 0.71 AU and reaching as far as 1.19 AU from the sun. Based on its brightness and the way it reflects light, 2020 CQ2 is probably between 0.003 to 0.015 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2020 CQ2's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.

2020 CQ2 has 19 close approaches predicted in the coming decades:

Images and Observations

2020 CQ2's orbit is determined by observations dating back to Feb. 15, 2020. It was last officially observed on Feb. 18, 2020. The IAU Minor Planet Center records 88 observations used to determine its orbit.

Accessibility and Exploration

2020 CQ2 can be reached with a journey of 378 days. This trajectory would require a delta-v of 8.052 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 94,330 potential trajectories and launch windows to this asteroid.
