Overview

463387 (2013 CT82) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 CT82 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2013 CT82 orbits the sun every 1,100 days (3.01 years), coming as close as 0.78 AU and reaching as far as 3.39 AU from the sun. Based on its brightness and the way it reflects light, 2013 CT82 is probably between 0.548 to 1.225 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.

Close Approaches

2013 CT82's orbit is 0.01 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.

2013 CT82 has 7 close approaches predicted in the coming decades:
