Overview

2009 BE58 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2009 BE58 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2009 BE58 orbits the sun every 331 days (0.91 years), coming as close as 0.41 AU and reaching as far as 1.46 AU from the sun. Based on its brightness and the way it reflects light, 2009 BE58 is probably between 0.121 to 0.272 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.

Close Approaches

2009 BE58'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.

2009 BE58 has 28 close approaches predicted in the coming decades:
