However, geological and atmospheric processes can alter these ratios through time. Over the past few decades, D\/H ratios in meteorites from Vesta and Mars, as well as from S- and C-type asteroids, have been measured. The aim of this article is to bring together all previously published data from these bodies, as well as the Earth, in order to determine the original D\/H ratio for each of these inner Solar System planetary bodies. Once all secondary processes have been stripped away, the inner Solar System appears to be relatively homogeneous in terms of water D\/H, with the original water D\/H ratios of Vesta, Mars, the Earth, and S- and C-type asteroids all falling between \u03b4D values of \u2212100\u2030 and \u2212590\u2030. This homogeneity is in accord with the \u2018Grand tack\u2019 model of Solar System formation, where giant planet migration causes the S- and C-type asteroids to be mixed within 1\u2009AU to eventually form the terrestrial planets.<\/p>\n<p>This article is part of the themed issue \u2018The origin, history and role of water in the evolution of the inner Solar System\u2019.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>L.
