There is so much confusion regarding the anomalous precession of Mercury's orbit. Mercury's orbit precesses at 575 arc-secs a century. Classical mechanics accounts for all except the anomalous 43 arc-secs. General relativity (curved space-time) accounts for the 43 secs. There are other theories which account for this anomaly in flat, Euclidean geometry. Some doubt that classical perturbation methods can correctly account for the full precession. Some tell us that radiation pressure can account for this anomaly as well. I can go on ... Can somebody tell me the orbital precession rate of the earth, Venus, Mars, Jupiter, or Saturn? I need it to check my new model of gravity.
