Asteroid mining is the hypothetical extraction of materials from asteroids and other minor planets, including near-Earth objects. [ 1 ] Notable asteroid mining challenges include the high cost of spaceflight , unreliable identification of asteroids which are suitable for mining, and the challenges of extracting usable material in a space ...
Approximately 8% of known main belt asteroids are similar in composition to 16 Psyche. [10] [11] One company, Planetary Resources, is already aiming to develop technologies with the goal of using them to mine asteroids. Planetary Resources estimates some 30-meter long asteroids to contain as much as $25 to $50 billion worth of platinum. [12]
Interest in asteroids – both for better understanding Earth’s origins and their composition, which could lay the groundwork for miners – is skyrocketing, and experts say asteroid mining may ...
AstroForge's ultimate goal in the field of asteroid mining is the extraction, refinement, and sale of platinum-group metals (PGMs) located within M-type asteroids near to Earth. These asteroids are expected to be quite small in comparison to main belt asteroids, being anywhere from around 20 to 300 meters in diameter.
The metallic M-type asteroid is notable for being significantly more radar-reflective than other asteroids. Radar measurements suggest it is composed of nickel and iron and that it was derived from the center of a much larger object that experienced melting and differentiation. The observed radar albedo was 0.58 and the optical albedo was 0.14. [8]

C-type (carbonaceous / ˌ k ɑːr b ə ˈ n eɪ ʃ ə s /) asteroids are the most common variety, forming around 75% of known asteroids. [1] They are volatile-rich and distinguished by a very low albedo because their composition includes a large amount of carbon, in addition to rocks and minerals. They have an average density of about 1.7 g/cm 3.
