2008 BT18 is a solar system 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 the 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. The primary component has a diameter of 600 m and a rotation speed of less than 3 hours.[2] The secondary component has a diameter of at least 200 m.
