Asteroid 2012 DA14 is likely to contain a variety of valuable resources including metals such as iron and nickel, and water which can be used in space as rocket fuel.
But because the space rock’s trajectory is tilted away from Earth, the cost of sending a probe to mine it would be too high to make such a pursuit worthwhile, experts said.
Asteroids are seen by some space companies as a valuable future resource which could supply fuel for interplanetary missions and provide metals to help build and repair satellites.
Water can be broken down into hydrogen and oxygen – two key components of rocket fuel – while metals could be used to engineer new or replacement parts for space equipment.
