(450894) 2008 BT18 is an asteroid discovered on 31 January 2008 by the LINEAR program at the Lincoln Laboratory at the Massachusetts Institute of Technology, which research identifies Near-Earth asteroids.
On 14 July 2008, the asteroid transited within 0.0151 AU of Earth, or 5.9 lunar distances.[1]
On 6 and 7 July 2008, research conducted using the Arecibo Observatory produced evidence that this is a binary asteroid.[3] The secondary component has a diameter of at least 200m, or about 33% the size of the primary.
