He also figured out the planet goes faster when it's at perihelion, nearer the sun, than when it's at aphelion, its furthest distance.

But eccentricity modulates the effect of precession (the alignment of perihelion and aphelion with solstices or equinoxes)(actually, obliquity does modulate this too, but while obliquity variations have significant effect by themselves, they are relatively small in proportion to the difference with zero obliquity, whereas Earth's eccentricity variations include getting near zero, where aphelion and perihelion would have no effect as they wouldn't exist.

The reason is that the greater total heat in joules applied to the hemisphere more oriented towards the Sun during perihelion (near Sun) turns out to be cancelled by the greater heat applied to the other hemisphere during aphelion (distant from Sun).
