The original method for solving the inverse incorrect problem of gravimetry is developed. The method allows to find the anomalous density structure of terrestrial planets from space-based observations of the gravity field and topography. Previously we used this method to study the internal structure and geodynamic characteristics of the Earth and Mars for the purpose of comparison and interpretation. In this paper the distribution of the compensation’s depths for the Earth’s topographical harmonics and lateral distributions of anomalous masses in selected depths are found with the help of this method. This distribution of anomalous masses is compared with similar distribution obtained using of seismic data for Earth’s Mohorovicic depths. The results obtained by these two methods give good coincidence. The maps of stresses’ distribution in the Earth’s lithosphere, obtained by our method, correspond to the map of earthquakes distribution. And the density distribution in the boundaries’ layers of the Earth’s core and mantle are in good agreement with the results of the analysis of free-oscillation data of the Earth. This gives reason to believe that our method provides a good model representation, which can be helpful as guidance in future studies on the surfaces of the terrestrial planets that are not available yet for seismic observations.
