Foreboding was the word the author was looking for, not forbidding.
Complications: Fix grammar and awkward wording. This paragraph could still use more work.

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