A space rock containing over 100 million tons of platinum at its core was seen flying within 1.5 million miles of the Earth this past weekend, sparking interest in the future of space mining.

This asteroid “2011 UW-158” flyby was captured by the Slooh online observatory, using a team of telescopes located in the Canary Islands. Two live feeds were provided; one long range that showed the asteroid moving across the viewing field visible as a small white spec, the other a close up centered on the asteroid. Commentary was provided by both Slooh astronomer Bob Berman, and host Eric Edelman.

A special guest appearance was made by Planetary Resources President Chris Lewicki. Planetary Resources is an asteroid mining venture – that counts Google founders Larry Page and Eric Schmidt among its backers – has its sights set on the 2011 UW-158. Due to the (relatively) close proximity of the asteroid, which is approximately six times farther than the Moon but 60 times closer than the next nearest planet, Venus, it has sparked a renewed interest in the viability of space mining.

The company has calculated the asteroid to contain about 100 million tons of pure platinum, approximately $5.4 trillion dollars’ worth. While they have also been tracking similar asteroids in our solar system, this is the one that has come the closest to the Earth.

Officials from NASA believe that futuristic space mining may be feasible as early as 2025. Asteroids would be “captured” and brought into orbit of our Moon, where space miners would be able to collect resources. NASA states that the elements present in asteroids, such as rocket fuel and water, could be gathered by future generations in the quest to explore more of our solar system.
