Overview

454101 (2013 BP73) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 BP73 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2013 BP73 orbits the sun every 559 days (1.53 years), coming as close as 0.49 AU and reaching as far as 2.16 AU from the sun. Based on its brightness and the way it reflects light, 2013 BP73 is probably between 0.217 to 0.485 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2013 BP73's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2013 BP73 has 15 close approaches predicted in the coming decades:
