Analysis of the Topography and Gravity Data for the Earth-like Venus

摘要

We consider the issue of choosing the reference surface for the analysis of data on the topography and the gravitational field of Venus. The hypothesis of the Earth-like Venus is used. The surface of an effectively equilibrium Venus, which survives from an earlier epoch, is chosen as a reference. For a set of the Earth-like models of the internal structure of Venus, the equilibrium figure parameters were calculated. The geoid heights and the gravitational force deviations from the hydrostatic equilibrium values were calculated for different regions.
