Overview

2020 CQ1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 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.

2020 CQ1 orbits the sun every 629 days (1.72 years), coming as close as 0.97 AU and reaching as far as 1.90 AU from the sun. Based on its brightness and the way it reflects light, 2020 CQ1 is probably between 0.030 to 0.130 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2020 CQ1'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 CQ1 has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Feb. 4, 2020 64,520 6.065
Dec. 3, 2038 28,344,875 10.687
Feb. 22, 2051 9,382,004 6.874

NASA Sentry has assessed impact risk for 11 very close approach scenarios. Here are the top scenarios ordered by probability of impact:

Images and Observations

2020 CQ1's orbit is determined by observations dating back to Feb. 5, 2020. It was last officially observed on March 5, 2020. The IAU Minor Planet Center records 48 observations used to determine its orbit.

Accessibility and Exploration

2020 CQ1 can be reached with a journey of 362 days. This trajectory would require a delta-v of 9.742 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 312 potential trajectories and launch windows to this asteroid.
