2018 CW2 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2018 CW2 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.
2018 CW2 orbits the sun every 242 days (0.66 years), coming as close as 0.44 AU and reaching as far as 1.08 AU from the sun. Based on its brightness and the way it reflects light, 2018 CW2 is probably between 0.020 to 0.044 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2018 CW2'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.
2018 CW2 has 36 close approaches predicted in the coming decades:
