Iron core of Mercury. Much larger proportionally than other planets (about 60% of its mass), making Mercury an Iron planet. Originally thought to have cooled early on, doubts occurred when Mariner 9 showed it had a magnetic field. Proven to be molten in 2007. Significant amount of a lighter element, such as sulfur, must be present in order to prevent its cooling. The magnetic field strength is about 1% that of Earth, so it must not have completely solidified. It has strong north-south assymetry, causing a lop-sided magnetic field.
