The earliest orbital observations have shown that the Moon has global asymmetry between its nearside and farside. The main differences are in topography, crustal thickness, and distribution of mare and highland areas. These asymmetries are thought to be a result of very early geological processes caused either by internal inhomogeneity and related thermochemical processes or by giant impact event(s). The evidence of both is present on the Moon surface. A joint analysis of the available data on the composition of lunar samples and meteorites and global geochemical and mineralogical mapping confirmed the existence of differences in the composition of the Moon’s nearside and farside. However, it is still impossible to unambiguously conclude about the origin of global asymmetry.
