The origin and early evolution of the Solar System has remained one of the most …(1)… questions for a long time. Numerous experimental and theoretical approaches have been employed to seek an …(2)… answer to this question. Owing to their unique chemistry and nearly …(3)… nature, meteorites constitute the most important accessible component of the Solar system material that may be analysed to unfold the story of the origin and early evolution of the Solar system. The most widely accepted model for the formation of the Solar system suggests that the gravitational collapse of a dense molecular cloud fragment about 4.56 Ga (Giga annum, meaning billion years) ago led to the formation of the proto-sun at its centre and a rotating disk of gas and dust, the so called Solar nebula, surrounding the …(4)… sun. The solar system objects (planets, satellites, comets and asteroids) formed out of this nebula in a gradual manner starting with the formation of grains that coagulated to form larger-sized objects that evolved to planetesimals and finally to planets through gravitational …(5)… and collision accretion processes. These events and processes were highly energetic, stochastic and occurred on a relatively short time scale of a few 100 kilo (thousand) years. Experimental records that provide clues to the various issues related to the formation of the Solar System are expected to be present in the first solids that formed in the Solar System known as Calcium, Aluminum-rich Inclusions (CAIs).
