Information on internal structure from shape, gravity field and rotation

Information on internal structure from shape, gravity field and rotation. Seismological information is available only for the Earth and in limited amounts for the Moon. Various geodetic data put constraints on the internal structure, but the ambiguity is much larger than for seismic data.
