Key Facts

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 0.582 to 1.300 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 6.60 hours.

2000 CK33's spectral type None (Tholen) / Xk (SMASSII) indicates that it is likely to contain iron, nickel, and cobalt.

No Close Approaches

2000 CK33's orbit is 0.13 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

2000 CK33's orbit is determined by observations dating back to Jan. 25, 2000. It was last officially observed on April 14, 2021. The IAU Minor Planet Center records 886 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
