Abstract / Description:The solar system formed about 4.6 billion years (b.y.) ago from condensation of matter inside a molecular cloud. Trying to reconstruct what happened is the goal of this chapter. For that, we combine our understanding of Galactic objects that will eventually form new suns and planetary systems with our knowledge on comets, meteorites, and small bodies of the solar system today. The specific tool we are using is molecular deuteration, namely the amount of deuterium with respect to hydrogen in molecules. This is the Ariadne's thread that helps us to find the way out from a labyrinth of possible histories of our solar system. The chapter reviews the observations and theories of the deuterium fractionation in prestellar cores, protostars, protoplanetary disks (PPDs), comets, interplanetary dust particles (IDPs), and meteorites and links them together to build up a coherent picture of the history of the solar system formation. We emphasize the interdisciplinary nature of this chapter, which gathers together researchers from different communities with the common goal of understanding solar system history.
