An asteroid the size of a cruise ship — 2012 DA14 — that will bypass our planet Friday could be worth almost $200 billion, according to prospective asteroid miners.

In relative space distances, the asteroid is cutting it close to Earth — 17,200 miles, or 15 minutes, from our planet. But miners say the asteroid's orbit makes it too difficult to chase down, according to a report posted by Fox News.
