Economics blog Centives used calculations on the density of a modern warship, they estimate that the first Death Star would have required 1.08×10 15 tons of steel.
That would use up all the iron in the Earth’s crust, and quite a bit from the Earth’s core that’s Assuming we could gather and refine all that iron a process that would take 833,000 years at today’s production rates and the value of the steel at current market prices would be around $852 quadrillion.
