摘要: This review discusses the current knowledge of gravity and geometry moon, their implications as to lunar structure. Measurements pertaining field are, first foremost, Doppler tracking spacecraft that have orbited but also laser ranging from earth moon meters accelerometers landed with Apollo spacecraft. include (1) those related shape: metric photography altimeters on 15, 16, 17; electromagnetic sounder landmark earlier orbiters; occupations, plus (2) measurements orientation: interferometry earth. The does not cover determinations topography taken for geologic or landing reconnaissance purposes. discussion tectonic is limited inferences a quantitative nature. emphasis work since 1970; see Kaula [1969, 1971] reviews work.
