Comparison between the geological features of Venus and Earth based on gravity aspects.

ABSTRACT: We probe the gravitational properties of two neighboring planets, Earth and Venus. To justify a comparison between gravity models of the two planets, spherical harmonic series were considered up to a degree and order of 100. The topography and gravity aspects, including [Formula: see text] (vertical derivative of the vertical component of the gravity field), strike alignment (SA), comb factor (CF), and I₂ invariant derived from the Marussi tensor, were calculated for the two planets at specifically selected zones that provided sufficient resolution. From Γ_zz we discovered that the N-NW edge of Lakshmi Planum does not show any subduction-like features. Its Γ_zz signature resembles passive continental margins on Earth, like those surrounding the Indian Peninsu
