Mercury/Core

Core of Mercury. Originally thought to have cooled early on, doubts occurred when Mariner 9 showed it had a magnetic field. Proven to be molten in 2007. Consists mostly of Iron, but a significant amount of a lighter element, such as sulfur, must be present in order to prevent its cooling. The magnetic field strength is about 10% that of Earth, so it must not have completely solidified.
