I don't think that moving the whole thing into our orbit would make much sense.
The biggest amount of delta-v is necessary to leave Earth's gravity well. Once you're there, going from and to asteroid is time-consuming but doesn't need that much delta-v, moving ore from the asteroid to Earth would cost some fuel, proportional to the mass.
So moving it into orbit would save time but require us to pay for the fuel all at once.
So why should someone do this, unless you need a permanent human presence on the asteroid?
- dylan604 2y agoI think we're all scared of the actual question posed or something as we've totally ignored it in everyone of these responses. Nobody cares in sci-fi about whether something should/could be done. That's not the purview of the plot. It's also not the purview of the original comment.

Unless there's a population of people living in space, the ore or products derived from ore need to eventually make their way to Earth in order to be worth while.
