ABSTRACT

The asteroids provide excellent opportunities to study the formation and early evolution of the Solar System. This is because they are small and can not retain heat efficiently, and thus cooled early in the Solar System and became “frozen” shortly after their formation. They are also widely regarded as the remnants of the planet formation, i. e., the planets were formed through collision between different asteroids, and thus the asteroids also record the early stage of planet formation. By studying the chemical and isotopic composition of different types of asteroids, we can gain important insight into the astrophysical environment of the Solar System formation and the formation process (e.g. the accretion time scale and the material source) of the planets.
