The giant impact hypothesis for the origin of the Moon has been widely accepted. One of the most important features of this hypothesis is that the impactor's metallic core was incorporated in the Earth after impact. If the mass of the impactor is 0.82 × 1027 g, the mass of the impactor core was estimated to be 0.19 × 1027 g, which is about 1/10 of present Earth's core. Liu (1982) derived the bulk composition of the Earth from CI chondrites, and concluded that the Fe content of his model appears… Expand

Planet atmospheric compositions are determined by the availability of a gas species, its molecular weight and the mass (or gravity force) of a planet. Both Mercury and the Moon are not massive enoughExpand

The probable chemical composition of the lunar globe is developed as far as can be done on the eve of a space age in which direct acquaintance with the object of the authors' study will largely supersede deductions made on theoretical grounds. Expand
