Overview

430804 (2005 AD13) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2005 AD13 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2005 AD13 orbits the sun every 994 days (2.72 years), coming as close as 0.48 AU and reaching as far as 3.42 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2005 AD13 is probably between 0.696 to 1.556 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

2005 AD13'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.

2005 AD13 has 10 close approaches predicted in the coming decades:
