Here is a relevant paper which may answer some of your questions: https://arxiv.org/abs/astro-ph/0102126 https://arxiv.org/abs/astro-ph/0102126 I've been slowly writing a paper about how to move planets by using repeated gravitational assists from masses moving in orbits which repeatedly cycle between inner and outer planets, conveying momentum from one planet to another. Unfortunately, I just don't have time to finish it right now. Feel free to email me if you want to discuss this stuff in more depth.

Very intersting, thanks. This could make a great sci-fi story, btw.

  There is a Chinese science fiction movie that is about this (although instead of slightly shifting the earth’s orbit, they make earth a spaceship itself) called The Wandering Earth. I believe it is on Netflix. The subtitles for the theatrical release were not the best I’ve ever seen but it was a fun movie.
