Orbital Analysis

The initial determinations of the variations in the lunar gravitational field are appreciably milder than those of the Earth in the sense of stress-implication, indicating a state closer to hydrostatic equilibrium. The variations determined also have a considerable correlation with the lunar topography, indicating a shallower origin than the Earth’s variations. The data are still insufficient to determine firmly the lunar oblateness, and thus help resolve the problem of the Moon’s moment of inertia.
