Overview

2003 BR47 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2003 BR47 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2003 BR47 orbits the sun every 759 days (2.08 years), coming as close as 0.81 AU and reaching as far as 2.44 AU from the sun. Based on its brightness and the way it reflects light, 2003 BR47 is probably between 0.129 to 0.288 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.

Close Approaches

2003 BR47's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2003 BR47 has 13 close approaches predicted in the coming decades:
