 note = {Impacts on the early Moon are expected to have been extremely asymmetrical between the leading and trailing hemispheres because of a fast orbital motion of the Moon. In this paper, suggested is an influence of the heavy asymmetrical bombardment upon the rotational dynamics of the early Moon. The preferential bombardment thinned the crust of the leading hemisphere and thickened that of the trailing hemisphere. As a consequence of the redistribution of crustal materials, the axis of the minimum principal moment of inertia shifted toward the west. The Moon was reoriented eastwards with the new minimum axis along the Earth-Moon line. The sequential actions operated continuously and concurrently on the early Moon, so that the Moon was gradually rotated toward the east. Longitudinal distributions of impact basins and crustal thickness models support the scenario proposed here., 資料番号: AA0047898001},
