The planet must be moved to an earth Lagrange point, and it must be provided with a moon. Mercury would be excellent in that role. Mercury is also a mining industry motherlode. Double bonus. Of course at this time we are unable to do much of anything on the moon, or even to capture an impact asteroid should one be coming our way. We don't have any capability to work in space, and we should get to work developing that capability. Venus is longterm, and we have a lot of technology to develop.

See? You've gone and proven my assertion! The majority of testing and development for those things will most probably occur via Mars colonization. Now, is that worthless?

If we actually had the technology to move a planet then something tells me we'd also have the technology to terraform every single rocky planet, moon, and asteroid in the solar system right where they are, complete with 10 nice hefty newtons per kilogram just like on earth.

In fact, we might as well just go with the whole Dyson sphere idea.
