Added general relativity tag. This is asking for a simplified form of a post-Newtonian expansion.

Oct 10, 2014 at 20:08 | comment | added | Zo the Relativist | @DeinFreund: If you're going to model the precession of Mercury, you can look into the Post-Newtonian formalism. It's basically a trick to approximate GR in a weak-field limit. For solar system stuff, you really only need the first couple of terms. | |
Oct 10, 2014 at 20:07 | comment | added | Zo the Relativist | @KyleKanos: MOND would be an acceleration-dependent effect. | |
Oct 10, 2014 at 19:57 | comment | added | DeinFreund | @KyleKanos I should test that, as it should make an impact on the small forces between planets. | |
Oct 10, 2014 at 19:43 | comment | added | DeinFreund | @JerrySchirmer planet-planet effects are included(that's what I meant by n-body simulation). You could call it relativistic effects, although it's not based on GR. Modeling the motion of the planets to fit observations fits better. | |

Oct 10, 2014 at 19:33 | comment | added | Kyle Kanos | Looks sorta like MOND. | |
Oct 10, 2014 at 19:33 | comment | added | Zo the Relativist | Are you trying to add general relativistic effects to Newtonian theory, or are you trying to empircally model the motions of the planets? Are you only considering the effects of the sun, or are you also considering planet-planet effects? | |
