对火星轨道变化问题的最后解释
t integration provides us with a ‘pseudo-ue’ solution of planetary orbital evolution. next, we compare the test integration with the main integration, n?1. for the period of 3 x 105 yr, we see a difference in mean anomalies of the earth between the two integrations of ~0.52°(in the case of the n?1 integration). this difference can be exapolated to the value ~8700°, about 25 rotations of earth after 5 gyr, since the error of longitudes increases linearly with time in the symplectic map. similarly
