Can Earth's motion be controlled

Answer 1

Earth's motion is already controlled by it's own, the sun's and the moon's gravity. Event's on earth also effect it's motion including earth quakes and other geological events. If you are asking whether humans could effect the motion of the earth, the question is, yes, with enough energy, we could control is dramatically. Mathematically, even the smallest things we do, like driving our cars, have some, however tiny, effect on the earth's motion.

It is unlikely, however, that we would ever be able to control the earth's movements entirely nor would we really want to.
