• By taking account of a size distribution of planetesimals, we show that noble gases gravitationally trapped by planetesimals in the solar nebula can explain the isotopic fractionation of terrestrial Xe relative to Xe in primitive meteorites, leaving Kr and other lighter noble gases almost unfractionated. However, this model is not successful in explaining noble gas elemental abundances in the Earth.
