where are s-type asteroids typically found in the solar system ​
Asteroid belt S-type (silicate-rich) asteroids are more common toward the inner region of the belt, within 2.5 AU of the Sun.[53][54] The spectra of their surfaces reveal the presence of silicates and some metal, but no significant carbonaceous compounds. This indicates that their materials have been significantly modified from their primordial composition, probably through melting and reformation. They have a relatively high albedo and form about 17% of the total asteroid population.
Formation and evolution of the Solar System The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun's formation.[28] The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar. Through direct contact, these grains formed into clumps up to 200 metres in diameter, which in turn collided to form larger bodies (planetesimals) of ~10Â kilometres (km) in size.[29] These gradually increased through further collisions, growing at the rate of centimetres per year over the course of the next few million years.[29]
