Ganymede City is a term coined by Arthur C. Clarke in his science fiction novel 3001: The Final Odyssey. It refers to two regions Lagash Sulcus and Memphis Facula on the surface of one of Jupiter’s moons Ganymede. When viewed from space these regions have a criss-crossing pattern of what appears to be streets and avenues. However these streets and avenues would be ten kilometers wide.
