The planet Mercury is comprised of different rocks and metals, including iron. It also has a core, which is thought to be made of iron.

The planet Mercury is mainly made from a rocky surface and metallic core. This accounts for about 75% of the planet.

Based on observing Mercury and comparing Mercury with Earth, it is inferred that Mercury has a large core that is rich in iron. Planetary geologists estimate that the core of Mercury is about 42% of the planet's total volume. Data from research performed by these geologists strongly suggests that the planet has a molten core. Mercury's core has a higher iron content than the core of any other major planet in the solar system.

Mercury is slightly smaller then the Earths Core. Mercury is believed to have been struck by a planet sized object billions of years ago which blew away everything but the core of the planet. (If Pluto was still a planet, Pluto would also be smaller than the Earth's core, but it was demoted to the status of a dwarf planet.)
