31. The research center developed XLim which was used at the origin of Aphelion developments in 1999. 32. When Neptune's eccentricity is large its aphelion can reach well beyond it current orbit. 33. The aphelion distance between the Earth's and Sun's centers is currently about or. 34. At aphelion in July the opposite holds, with TCG ticking faster than it does on average. 35. Currently, perihelion occurs during the southern hemisphere's summer and aphelion during the southern winter. 36.
