Detailed explanation-1: -The S-types ("stony") are made up of silicate materials and nickel-iron. The M-types are metallic (nickel-iron). The asteroids’ compositional differences are related to how far from the Sun they formed.
Detailed explanation-2: -Minerals that can be found in asteroids are: iron, nickel, iridium, palladium, platinum, gold, and magnesium to name a few. Metal, however, is not the only thing that would be mined from asteroids.
Detailed explanation-3: -Belt composition. Most of the asteroids in the main belt are made of rock and stone, but a small portion of them contain iron and nickel metals. The remaining asteroids are made up of a mix of these, along with carbon-rich materials.
Detailed explanation-4: -Asteroids are diverse in composition; some are metallic while others are rich in carbon, giving them a coal-black color. They can be “rubble piles, ‘’ loosely held together by their own gravity, or they can be solid rocks. Most of the asteroids in our solar system reside in a region called the main asteroid belt.
