Title: Exchange of condensed matter among the outer and terrestrial protoplanets and the effect on surface impact and atmospheric accretion

Abstract

The potential contribution of volatile material to planetary atmospheres from comet impact is presently estimated on the basis of a scenario of extensive gravitational scattering of icy planetesimals from the other planets and cometary nuclei in the early and late phase of the bombardment process. In the earth's case, the cometary water is sufficient to compete with the water contained in the nonvolatile planetesimals condensed in the region of the terrestrial planets; the same consideration could be applied to Mars and Venus, although it is not yet clear how the cometary chemical compositions may have affected the evolution of early planetary atmospheres. 52 references.
