SOLAR SYSTEM

Detailed explanation-1: -S-type asteroids consist mainly of nickel-iron and magnesium-silicates/stony materials. They are moderately bright, having an albedo of typically 0.20.

Detailed explanation-2: -They are often found on the inner edge of the Main Belt and contribute almost 20% of its bodies. Compared to Type C, they are quite bright and easier to see. Juno, one of the largest asteroids in the Main Belt, and 433 Eros, the first asteroid in history where a probe landed, are good examples of Type S asteroids.

Detailed explanation-3: -C-type asteroids are chondrite asteroids, largely composed of clay and carbon compounds as well as silicate rocks. S-type asteroids are stony (silicate rock) asteroids that also contain some metallic minerals.

Detailed explanation-4: -S-types (stony) are made up of silicate materials and nickel-iron, and accounts for about 17 percent of known asteroids. They are brighter than C-type and they dominate the inner asteroid belt. M-types (metallic) are made from nickel and iron and accounts for about 8 percent of known asteroids.
