EARTH
Eris is the largest dwarf planet, about 25% larger than Pluto.
Its possible that there was once a vast civilization on mars. And due to changes on the red planet( whether it be climactic changes, or something else) the metals used in that vast world wide civilization( probably a giant city that covered the planet) eroded away leaving behind nothing but the reddish iron oxide on the planet.
Alchemists believed lead to be the oldest metal. It was associated with the planet Saturn. Lead was once refered to as "salt of Saturn" by alchemists and early chemists
