Overview
363067 (2000 CO101) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 CO101 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2000 CO101 orbits the sun every 408 days (1.12 years), coming as close as 0.98 AU and reaching as far as 1.17 AU from the sun. Based on its brightness and the way it reflects light, 2000 CO101 is probably between 0.250 to 1.119 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
The rotation of 2000 CO101 has been observed. It completes a rotation on its axis every 5.12 hours.
2000 CO101's spectral type None (Tholen) / Xk (SMASSII) indicates that it is likely to contain iron, nickel, and cobalt.
Close Approaches
2000 CO101's orbit is 0.02 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.
2000 CO101 has 22 close approaches predicted in the coming decades:

Images and Observations
2000 CO101's orbit is determined by observations dating back to Feb. 4, 2000. It was last officially observed on April 22, 2020. The IAU Minor Planet Center records 1,146 observations used to determine its orbit.
Accessibility and Exploration
2000 CO101 can be reached with a journey of 362 days. This trajectory would require a delta-v of 11.081 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 61 potential trajectories and launch windows to this asteroid.
