In **perturbation** is the complex motion of a ^{[1]} The other forces can include a third (fourth, fifth, etc.) body, ^{[2]}

The study of perturbations began with the first attempts to predict planetary motions in the sky. In ancient times the causes were a mystery. ^{[2]} recognizing the complex difficulties of their calculation.^{[3]} Many of the great mathematicians since then have given attention to the various problems involved; throughout the 18th and 19th centuries there was demand for accurate tables of the position of the

The complex motions of gravitational perturbations can be broken down. The hypothetical motion that the body follows under the gravitational effect of one other body only is typically a **perturbations** due to the additional gravitational effects of the remaining body or bodies. If there is only one other significant body then the perturbed motion is a *n*-body problem^{[4]}

Most systems that involve multiple gravitational attractions present one primary body which is dominant in its effects (for example, a
