Question

Which asteroid type is identified by a high concentration of iron-nickel alloys and would be the primary target for sourcing structural metals?

Accepted Answer

The asteroid type identified by a high concentration of iron-nickel alloys is the M-type asteroid, or metallic asteroid. These asteroids are the primary target for sourcing structural metals because they are composed almost entirely of metal, originating from the exposed cores of shattered planetesimals—the smaller building blocks that collided to form planets in the early solar system. Think of an M-type asteroid like the center of a peach; just as the stone is the densest, metallic core of the fruit after the softer outer layers are removed, these asteroids represent the dense, iron-rich core left behind after a larger body’s rocky exterior was stripped away by ancient impacts. Their composition is remarkably similar to the Earth&#x27;s own iron core, providing a vast, easily accessible supply of industrial-grade metals like iron, nickel, and precious metals such as cobalt or platinum, which are essential for large-scale space construction.
