2004 FU162 is an Aten near-Earth asteroid less than 20 meters in diameter crudely estimated to have passed roughly 6500 km above the surface of Earth on 31 March 2004.
It was only observed for 44 minutes on 31 March 2004, by the Lincoln Near-Earth Asteroid Research (LINEAR) team at Lincoln Laboratory's Experimental Test Site in Socorro, New Mexico, and remains a lost asteroid. The estimated 4 to 6 meter sized body made one of the closest known approaches to Earth.
