Beschreibung:
Current knowledge about the gravity and geometry of the moon is discussed which has been obtained by Doppler tracking of lunar orbiters, laser ranging, metric photography, and various instruments landed on the moon. Determinations of spherical harmonic coefficients of the lunar gravitational field are described, significant features observed in the field are noted (including the Orientale complex), and measurements of physical librations are reviewed. Systems for determining the lunar geometry and topography are described along with their intrinsic disadvantages. Tectonic implications of the lunar gravitational field and shape are discussed in regard to thermal evolution, marked variations in elevations, crustal and mascon formation, and volcanism.
