    The core is composed mostly of iron (with about 10% sulfur in the outer core), with the outer core in a molten state due to the extreme heat, and the inner core in a solid state due to the extreme pressure. The core is estimated to have a temperature of 3700 C (outer core) to 4300 C (inner core).
