The minds behind science fiction books and movies have been creating artificial worlds for decades, but what would it take to make one for real?

Popular Mechanics recently looked into the ins and outs of constructing a whole new environment, and with the help of NASA engineering fellow Adam Steltzner nailed down some specifics.

Given the size requirement of constructing a new planet, it was cast aside immediately in favor of something more manageable, like the Star Wars Death Star.

It wouldn’t offer the stability that a whole planet does, but at only about 75-miles in diameter, it’s certainly the more approachable idea.

Even that, it was decided, would be more than Earth and its inhabitants are currently capable of doing.

One is that the amount of steel needed to build it just isn’t currently available. Given average annual production rates, it would take around 800 thousand years to come up with the materials.

The cost of the project was estimated to be 13 thousand times greater than the world’s current combined gross domestic product.

The other option is to create a new Earth from scratch. A 2005 study suggested we launch a massive super-fusion facility close to the sun to harvest hydrogen and create extremely dense elements that would then be blasted into prime areas of space, and wait while nature builds one itself, a process that could take tens of thousands of years. In the end, neither option seems particularly feasible.
