Overview
136617 (1994 CC) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1994 CC as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
1994 CC orbits the sun every 766 days (2.10 years), coming as close as 0.96 AU and reaching as far as 2.32 AU from the sun. Based on its brightness and the way it reflects light, 1994 CC is probably between 0.677 to 1.514 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 1994 CC has been observed. It completes a rotation on its axis every 2.39 hours.
Close Approaches
1994 CC'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.
1994 CC has 9 close approaches predicted in the coming decades:
