Earth group planets gravitational models of 3-d density distributions

In the paper the interpretation of planetary anomalies in the gravitational field of the Earth, Venus, Mars and Moon in their relationship with the internal inhomogeneous structure of those planets is considered. The model of the gravitational field of named planets up to 20th order and degree and the three-layer models (crust, mantle and core) of the planets and its planetary parameters was taken as the initial information for modelling.
