Iron is notable for being the final element produced by stellar nucleosynthesis, and thus the heaviest element which does not require a supernova or similarly cataclysmic event for its formation. It is therefore the most abundant heavy metal in the universe. Mars is the planet with a liquid iron center.
Iron is the most abundant metal on Earth, and is believed to be the tenth most abundant element in the universe. Iron is also the second most abundant element by mass, making up 34% of the mass of the Earth; the concentration of iron in the various layers of the Earth ranges from high at the inner core to about 5% in the outer crust. It is possible the Earth's inner core consists of a single iron crystal, although it is more likely to be a mixture of iron and nickel. The large amount of iron in the Earth is thought to create its magnetic field.
Rust is iron oxidized
