Newly-discovered asteroid 2009 BD is slowly passing by Earth today only 400,000 miles away. The small 10m-wide space rock poses no threat, but it merits attention anyway. The orbit of 2009 BD appears to be almost identical to the orbit of Earth. 2009 BD may be a rare co-orbital asteroid, circling the sun in near-tandem with our planet. Extrapolating the motion of 2009 BD into the future, we see that it remains in the vicinity of Earth for many months to come, never receding farther than 0.1 AU (9.3 million miles) until Nov. 2010
