Overview
86450 (2000 CK33) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2000 CK33 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.
2000 CK33 orbits the sun every 348 days (0.95 years), coming as close as 0.57 AU and reaching as far as 1.37 AU from the sun. Based on its brightness and the way it reflects light, 2000 CK33 is probably between 0.540 to 1.208 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 CK33 has been observed. It completes a rotation on its axis every 6.61 hours.
2000 CK33's spectral type None (Tholen) / Xk (SMASSII) indicates that it is likely to contain iron, nickel, and cobalt.
Close Approaches
2000 CK33's orbit is 0.13 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 CK33 has 12 close approaches predicted in the coming decades:
