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.
2022 OB 5 is a small near-Earth asteroid that passed within 0.00679 AU (1,016,000 km) from Earth on 5 August 2022. [2] It is the primary target of AstroForge's Brokkr-2 (Odin) mission, which is planned for launch alongside IM-2 by February 2025, reaching the asteroid around December 2025. [3]
With minerals in short supply on Earth, private companies such as California-based AstroForge and international space agencies are turning to the prospect of asteroids in space.
Twelve asteroids made up the initially identified group, all of which could be potentially mined with present-day rocket technology. Of 9,000 asteroids searched in the NEO database, these twelve could all be brought into an Earth-accessible orbit by changing their velocity by less than 500 meters per second (1,800 km/h; 1,100 mph). The dozen ...
These asteroids, while smaller than the dinosaur killer, struck our planet about 25,000 years apart. They left miles-long craters in the Mid-Atlantic Chesapeake Bay and Siberia: the fourth- and ...

Asteroids are ripe for mining. Some contain gold or platinum. Others could help make rocket fuel. When they're mini-moons, that's a prime opportunity.
Outside the top four, the ranking of all the asteroids is uncertain, as there is a great deal of overlap among the estimates. The largest asteroids with an accurately measured mass, because they have been studied by the probe Dawn, are 1 Ceres with a mass of (939.3 ± 0.5) × 10 18 kg, and 4 Vesta at (259.076 ± 0.001) × 10 18 kg.
