Jan 5, 2020 at 19:25 comment added jamesqf You could theoretically use a chain of gravity tractors, e.g. disturb the orbit of a small asteroid so that it affects a larger one in just the right way to affect a still larger one, eventually working up to directing a Jovian moon (or similar-sized body) towards the Moon.

Back in my first college physics class, our professor actually discussed this question and according to his calculations there would be no noticeable affect on Earth's orbit.
