Overview

385605 (2005 EJ225) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2005 EJ225 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2005 EJ225 orbits the sun every 814 days (2.23 years), coming as close as 0.73 AU and reaching as far as 2.68 AU from the sun. Based on its brightness and the way it reflects light, 2005 EJ225 is probably between 0.431 to 0.964 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 EJ225'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 EJ225 has 8 close approaches predicted in the coming decades:
