This 13-pound, 3.6 foot metal ball fell from the sky in the Republic of Namibia in southern Africa last month. Nobody has claimed ownership. From CNN:
"Mysterious metal ball from space falls in Namibia"
Paul Ludik, director of the country's National Forensic Science Institute, told The Namibian the sphere… is made of a "sophisticated" metal alloy that is known to man, but he said it has no markings that would identify it…
Ludik told The Namibian that the object poses no cause for alarm, and that such reports of metallic spheres falling from space are common in the Southern Hemisphere.
