Overview

364136 (2006 CJ) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2006 CJ as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2006 CJ orbits the sun every 203 days (0.56 years), coming as close as 0.17 AU and reaching as far as 1.19 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2006 CJ is probably between 0.242 to 0.542 kilometers in diameter, making it small in absolute terms, but larger than 90% of asteroids, very roughly comparable in size to a football field.

Close Approaches

2006 CJ's orbit is 0.03 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.

2006 CJ has 59 close approaches predicted in the coming decades:
