Overview

230111 (2001 BE10) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2001 BE10 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2001 BE10 orbits the sun every 273 days (0.75 years), coming as close as 0.52 AU and reaching as far as 1.13 AU from the sun. Based on its brightness and the way it reflects light, 2001 BE10 is probably between 0.400 to 0.400 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 2001 BE10 has been observed. It completes a rotation on its axis every 4.19 hours.

Close Approaches

2001 BE10's orbit is 0.04 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2001 BE10 has 20 close approaches predicted in the coming decades:
