In case highest accuracy is needed things get much more complex. In the case of comets non gravitational forces (radiation pressure and gas drags) are to be taken into account. In the case of Mercury relativity effects cannot be ignored. Then also the total energy is no longer a constant (because the four vector energy with linear momentum is). The finalfinite speed of light also makes it important to allow for light-time effects, both classical and relativity. Planets can no longer be considered as particles but their shape and density must be considered too. For example the flattening of the Earth causes precession, which causes the axial tilt to change, which has its effects on the longterm movements of all planets.
