Moon's Core Similar to Earth's, Study Reveals

Recent studies on the Moon's interior suggest the presence of a solid inner core and a mantle overturn caused by the rheology of ilmenite. Seismic detection and tidal constraints have provided evidence for a low-viscosity zone at the core-mantle boundary, which may be responsible for strong tidal heating. The Moon's interior structure has implications for its thermal and chemical evolution, as well as the preservation of its magnetic dynamo.
