Overview

454100 (2013 BO73) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 BO73 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2013 BO73 orbits the sun every 561 days (1.54 years), coming as close as 0.77 AU and reaching as far as 1.89 AU from the sun. 2013 BO73 is about 0.5 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

The rotation of 2013 BO73 has been observed. It completes a rotation on its axis every 1.10 hours.

Close Approaches

2013 BO73'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.

2013 BO73 has 16 close approaches predicted in the coming decades:
