Overview

381906 (2010 CL19) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 CL19 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2010 CL19 orbits the sun every 700 days (1.92 years), coming as close as 0.55 AU and reaching as far as 2.54 AU from the sun. 2010 CL19 is about 0.5 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

The rotation of 2010 CL19 has been observed. It completes a rotation on its axis every 3.52 hours.

Close Approaches

2010 CL19'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.

2010 CL19 has 10 close approaches predicted in the coming decades:
