Overview

322756 (2001 CK32) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2001 CK32 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.

2001 CK32 orbits the sun every 225 days (0.62 years), coming as close as 0.45 AU and reaching as far as 1.00 AU from the sun. Based on its brightness and the way it reflects light, 2001 CK32 is probably between 0.421 to 0.942 kilometers in diameter, making it small in absolute terms, but larger than ~97% of asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2001 CK32's orbit is 0.08 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.

2001 CK32 has 25 close approaches predicted in the coming decades:
