Energies Emitted in Reconstruction of Venus, Mars, and Mercury

Jun Iriyama, Masaaki Yamamura

Abstract

The loss of gravitational energy on core formation is calculated for Venus, Mars, and Mercury. The energy is 1.02×1038 ergs, 1.10×1036 ergs, and 1.34×1036 ergs for Venus, Mars, and Mercury, respectively. This is equivalent to an average rise of temperature of 1600°, 130°, and 310° for Venus, Mars, and Mercury, respectively.The results show that the energy released by the formation of iron core of Venus may play an important role in the thermal structure.
