Scientific paper

Asteroids, comets, meteorites and IDPS, are generally believed to have contributed to the volatile inventory of the terrestrial planets. About 1 weight-% of carbonaceous meteorites, which are thought to be fragments of asteroids, can be extracted with solvents in the form of separable compounds. Some of these compound might have been important starting materials for the chemical evolution of the early Earth (and potentially Mars). Interplanetary dust particles (IDPs), sub-millimeter sized particles that contain up to 40% organic carbon, are associated with comets and are thought to have contributed a large fraction to the inventory of volatiles found on the terrestrial planets. We sumamrize the organic composition of carbonaceous chondrites, asteroids and comets may have played in the delivery of these organic compounds to the early Earth and other solar system bodies.
