Overview

525356 (2005 BG14) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2005 BG14 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2005 BG14 orbits the sun every 1,030 days (2.82 years), coming as close as 0.54 AU and reaching as far as 3.44 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2005 BG14 is probably between 0.488 to 1.092 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 BG14's orbit is 0.03 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 BG14 has 8 close approaches predicted in the coming decades:
