	Iron is one of the most abundant elements on earth and in space. There are pure iron asteroids, remnants of the never formed core of the dwarf-planet Ceres that couldn't become to a proper planet due to the gravitational disturbances caused by ~~Jupiter~~ proximity. There's so much iron everywhere because irons nuclear core has the highest binding energy. This is putting iron at the end of the stellar fusion process where it piles up (along with [[nickel]]).
