Overview
2014 CH13 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 CH13 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.
2014 CH13 orbits the sun every 438 days (1.20 years), coming as close as 0.98 AU and reaching as far as 1.27 AU from the sun. Based on its brightness and the way it reflects light, 2014 CH13 is probably between 0.020 to 0.090 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2014 CH13'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.
2014 CH13 has 22 close approaches predicted in the coming decades:

Images and Observations
2014 CH13's orbit is determined by observations dating back to Feb. 10, 2014. It was last officially observed on Aug. 14, 2020. The IAU Minor Planet Center records 39 observations used to determine its orbit.
Accessibility and Exploration
2014 CH13 can be reached with a journey of 354 days. This trajectory would require a delta-v of 6.585 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 289,550 potential trajectories and launch windows to this asteroid.
