S-Type

An S-Type asteroid is a common class of space rocks that have a somewhat shiny, stony surface. They are composed mainly of silicate minerals like olivine and pyroxene, giving them a rocky appearance. These asteroids usually have an intermediate size, ranging from a few hundred meters to several kilometers across. Their surfaces reflect sunlight, making them more visible than darker types. S-Types are important because they provide clues about the composition of the early solar system and may serve as potential targets for mining or space exploration missions.
