We compare the evolution of Mercury’s eccentricity in published Solar System integrations. These data sets are affected to different degrees by numerical chaos, because of how well they resolve Mercury’s pericenter passage. We find statistically significant differences between two data sets, in the eccentricity distribution of Mercury over time. We also study pericenter resolution in a variety of symplectic maps used in the literature.
