Iron is a relatively abundant element in the universe, found in stars and planets in considerable quantity, with very stable nuclei. The core of the Earth is largely composed of iron, with about 10 percent occluded hydrogen. Iron is also the fourth most abundant element, by mass, making up the crust of the Earth.
Iron is a vital constituent of plant and animal life, and appears in blood hemoglobin, causing human and humanoid blood to be colored red.
Iron is a principal component of meteorites known as siderites and is also a component of carbon steel.
