An artist's conception of the Feb. 15 flyby of asteroid 2012 DA14.
The 150-foot-wide (45 meters) asteroid 2012 DA14 — which will zoom within 17,200 miles (27,000 kilometers) of Earth on Friday, marking the closest approach by such a large space rock that astronomers have ever known about in advance — may harbor $65 billion of recoverable water and $130 billion in metals, say officials with celestial mining firm Deep Space Industries.
That's just a guess, they stressed, since 2012 DA14's composition is not well known and its size is an estimate based on the asteroid's brightness.
