Maybe you want to destroy it: a significant number of methods for destroying the Earth involve moving it by some substantial amount. Alternatively, as the Earth's angular kinetic energy is negligible compared to its orbital kinetic energy, you might consider diverting a relatively small amount of resources to simply stopping the Earth from spinning at all, before beginning the main project. You could reuse the same asteroid again and again, looping it around a few gas giants and back to gain lots more kinetic energy from those gas giants in the same way that Earth just gained velocity from the rock. This can be employed to move the Sun and Earth in tandem to a place where the Earth can more easily be destroyed. How can order on a small scale produce chaos on a larger scale? If there was some way to electrically charge the Earth, by dumping lots of identically charged particles onto the Earth or just ionizing particles already on Earth - a large amber rod might perhaps be in order - then we could use magnetic fields to drive the planet in the direction we wanted it to go.

Direct matter propulsion. Same method as above, just using gigantic mass drivers/railguns to fire huge quantities of matter away from Earth, instead of a rocket exhaust. Ceres, the solar system's largest asteroid, has less than 1/40,000th the mass of Earth; the Moon, a mere 1/80th. These objects are the heaviest you're likely to find - there are heavier moons and entire planets you could consider using, but to be honest from this point of view it looks more like using a succession of hundreds, thousands or tens of thousands of smaller asteroid impacts would be a better bet. It all depends how fussy you are about how the Earth looks afterwards, of course. Wait long enough, and the solar wind blowing the sail outwards will take the Earth outward too, since the two are gravitationally bound together! It is possible to use a solar sail to steer the Earth into the Sun. It involves asteroids, like the above method, only instead of direct impacts, this time we just steer them past the Earth, allowing rock and planet to exchange a little momentum, with the result of an Earth moving on a slightly different track and an asteroid moving on a significantly different one.

Rather than simply bouncing off, the object destroyed much of both itself and Earth, causing a VAST spray of matter to be hurled off from the impact point; this matter coagulated into what is now the Moon. Certainly, no single impact is going to do all the course changing you'll be wanting to pull off. Solar sail method. I can't honestly add much to that article except to say that to move the Earth substantially, the sail used is going to have to be pretty big. Construct a huge solar sail with a significant mass. Maybe. Or better yet: the Earth already has a standing magnetic field; perhaps we could construct a cylinder of cable around it, and pass current to move it using Lorentz forces. Plan it right, and you can couple it together with the Earth with gravity alone, using the solar wind to balance out the Earth's gravitational attraction. This structure would not be in orbit around the Sun, but static, remaining aloft using the radiation pressure of catching and reflecting solar energy. Build an enormous lightweight "hat" for the Sun, which catches the Sun's rays. Belgium. Design them carefully so that when used the rocket engines do not actually just propel themselves through the ground and into Earth where they become useless - you may need to periodically dig them out again after several thousand years' continued thrusting, or else just build new ones over the top.

You could repeat this thousands of times over the course of millions of years. Billiards method. Clonk the Earth with something big and heavy, causing it to alter course. And lastly, suppose that they all jumped at precisely the same instant, which of course they will not, seeing as the time difference between the fastest watch and the slowest will likely be over five minutes. As long as they're tiled, you'll have the same pattern but larger. Or, alternately, you could dress the ladies like tramps and have an authentic frat-party. Note that the Earth does not and will not behave like a solid, rigid billiard ball under such huge impacts as these. Please note that the swim and formal doors don't change your sims to their personal formals, rather to a random outfit from the trunk. No more telling everyone on the lot to stop what they're doing and come over to change clothes, now they'll do it just walking through the door! The principle here is much the same, with the railguns behaving somewhat like discretized versions of thrusters, providing instantaneous changes in velocity as opposed to sustained steady change.
