Asteroid mining - Wikipedia

Asteroid mining is the exploitation of raw materials from asteroids and other minor planets, including near-Earth objects.. Hard rock minerals could theoretically be mined from an asteroid or a spent comet. Precious metals such as gold, silver, and platinum group metals could be transported back to Earth, while iron group metals and other common ones could be used for construction in space.. Difficulties
