rence 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， the longitude error of pluto can be estimated as ～12°. this value for pluto is much better than the result in kinoshita & nakai (1996) where the difference is estimated as ～60°.
