2009 BD is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2009 BD as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
2009 BD orbits the sun every 400 days (1.10 years), coming as close as 1.01 AU and reaching as far as 1.12 AU from the sun. Based on its brightness and the way it reflects light, 2009 BD is probably between 0.004 to 0.019 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2009 BD'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 BD has 21 close approaches predicted in the coming decades:

2009 BD's orbit is determined by observations dating back to Jan. 16, 2009. It was last officially observed on June 20, 2011. The IAU Minor Planet Center records 180 observations used to determine its orbit.
2009 BD can be reached with a journey of 362 days. This trajectory would require a delta-v of 4.729 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 1,333,685 potential trajectories and launch windows to this asteroid.
