Final answer:
S-Type asteroids are most likely the source of Ordinary Chondrites, a common type of Stony Meteorite. These asteroids are characterized by their silicate-rich composition and lack of carbon compounds, distinguishing them from other asteroid types.
Step-by-step explanation:
S-Type asteroids may be the source of Ordinary Chondrites, a type of Stony Meteorite. These asteroids are characterized by a stony or silicate composition and lack the dark carbon compounds found in C-type asteroids, resulting in higher reflectivity and the presence of clearer spectral signatures of silicate minerals. S-type asteroids are considered chemically primitive and are believed to have formed in a different location in the solar system than C-type asteroids.
The majority of meteorites that reach Earth are primitive stones, with some being classified as carbonaceous meteorites containing carbon and complex organic molecules. S-type asteroids, on the other hand, are thought to be the parent bodies of the more common non-carbonaceous stony meteorites. It is significant that meteorites like ordinary chondrites are not just space debris but are primitive objects from the formation of the solar system about 4.5 billion years ago, holding valuable information about the early conditions. The S-type asteroids differ from M-type asteroids, which are mostly metallic and can reflect radar signals better due to their metal composition.
