-{{cite|In methods of special perturbations, numerical datasets, representing values for the positions, velocities and accelerative forces on the bodies of interest, are made the basis of numerical integration of the differential equations of motion.[6] In effect, the positions and velocities are perturbed directly, and '''no attempt is made to calculate the curves of the orbits or the orbital elements.'''[2] Special perturbations can be applied to any problem in celestial mechanics, as it is not limited to cases where the perturbing forces are small.[4] Once applied only to comets and minor planets, '''special perturbation methods are now the basis of the most accurate machine-generated planetary ephemerides of the great astronomical almanacs.'''[2][7]}}
