Scott Manley had a recent video talking about the work involved in moving the Earth, that you might find interesting. Basically the most "plausible" approach might be to move the moon and use it to drag the Earth. Similarly the best way to move another large object might be to carefully move other objects small amounts to do precise gravity assists.

- smegger001 5y agowouldn't that require a solution to the three body problem to make such precise gravity assists?
- ericbarrett 5y agoOnly if the target was far and we did it in one shot. Otherwise you’d just measure the state of things and make corrections for your next maneuver, the way we do for trips outside Earth’s orbit today.
- kbelder 5y agoWhile we can't 'solve' the three body problem, we can make increasingly accurate estimations. Enough to usually get orbital mechanics right in the short-term. For a setting where we were getting it right until we got it wrong, see Niven's "A World out of Time".
