Comparing the interiors of Earth and Mercury

Comparing the interiors of Earth and Mercury
Comparing the interiors of Earth and Mercury Mercury is a far more metal- and sulfur-rich planet than Earth is. Its metallic core dominates its interior. The exact size of the core, how much of it is liquid, and what kind of material exists at the core-mantle boundary are still not well understood; BepiColombo hopes to understand Mercury's interior better.
