The Earth' trajectory is a stable trajectory. if a asteroid hit it, it will oscillate a while then eventually it goes on its previous trajectory.  You can get it with calculation Sun-Earth potential energy. it is like a rock placed on top of a mountain. If you kick it slowly then it will fall. But if it is on the bottom, it will not be moved very easily..

exactly like oksuz.. unles ofcourse u hit it with a very high velocity.. in which case it does get knocked off orbit and would escape (called escape velocity)
