Overview

202683 (2006 US216) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2006 US216 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2006 US216 orbits the sun every 186 days (0.51 years), coming as close as 0.28 AU and reaching as far as 1.00 AU from the sun. Based on its brightness and the way it reflects light, 2006 US216 is probably between 0.291 to 0.652 kilometers in diameter, making it small in absolute terms, but larger than 90% of asteroids, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

2006 US216's orbit is 0.04 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 US216 has 43 close approaches predicted in the coming decades:
