SOLAR SYSTEM

Detailed explanation-1: -The C-type (chondrite) asteroids are most common. They probably consist of clay and silicate rocks, and are dark in appearance. They are among the most ancient objects in the solar system. The S-types ("stony") are made up of silicate materials and nickel-iron.

Detailed explanation-2: -Stony MeteoritesStony meteorites are made up of minerals that contain silicates-material made of silicon and oxygen. They also contain some metal-nickel and iron. There are two major types of stony meteorites: chondrites and achondrites.

Detailed explanation-3: -Asteroid composition varies widely, from volatile-rich bodies to metallic bodies with high concentrations of rare metals such as gold, silver, and platinum in addition to more common elements such as iron and nickel.

Detailed explanation-4: -Asteroids are made mostly of rock-with some composed of clay and silicate-and different metals, mostly nickel and iron.

Detailed explanation-5: -Meteoroids are lumps of rock or iron that orbit the sun, just as planets, asteroids, and comets do.
