Overview

531899 (2013 BE19) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2013 BE19 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2013 BE19 orbits the sun every 318 days (0.87 years), coming as close as 0.64 AU and reaching as far as 1.18 AU from the sun. Based on its brightness and the way it reflects light, 2013 BE19 is probably between 0.294 to 0.658 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

The rotation of 2013 BE19 has been observed. It completes a rotation on its axis every 115.00 hours.

Close Approaches

2013 BE19's orbit is 0.04 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 BE19 has 14 close approaches predicted in the coming decades:
