A series of three-layer models for the internal structure of Venus is calculated based on an earth model with account taken of the difference in temperatures and phase transition depths in the interiors of earth and Venus. The total iron content in Venus has been estimated for probable variations in the composition of its mantle and core. It is shown that in the Venus models with an iron core, the total iron content is larger than in the earth if the mantle of Venus is richer in iron than is the mantle of the earth. Assuming such a model for Venus, the regularity in the decrease of the total iron content with increasing distance from the sun is not violated. Distributions of the parameters for the most probable Venus model are given.
