Decades of planetary exploration/observation missions have provided data on all planets in our solar system and their various satellites, with the addition of exoplanets in recent years. The data reveal not only the atmospheres and surface environments of these bodies but also contain a substantial amount of information about their interiors. Prime examples concerning planetary interiors are the geodetic data that constrain the density distributions of planets and magnetic field records that indicate the presence of electrically conducting fluids, which are essential elements for building physical and chemical models of the interior of planets. To understand the interior regions that account for most of the mass of planetary bodies, it is essential to combine constraints from these observations with physical properties from mineralogical studies and interior models based on these properties.<br/>This session aims to share current understanding and future developments obtained through multidisciplinary methods by inviting research on the interiors of all types of planets, as well as their satellites. We welcome presentations from various fields including but not limited to: observations, sample analyses, experiments, numerical calculations, and geophysical/geochemical modeling. In addition to planets and satellites of the solar system, we also invite research on exoplanets.
