Overview

453729 (2011 BO24) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2011 BO24 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2011 BO24 orbits the sun every 593 days (1.62 years), coming as close as 1.00 AU and reaching as far as 1.76 AU from the sun. Based on its brightness and the way it reflects light, 2011 BO24 is probably between 0.456 to 1.019 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

2011 BO24'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.

2011 BO24 has 10 close approaches predicted in the coming decades:
