Otherwise difficult to notice, the change in the Sun's apparent diameter between Perihelion and Aphelion is clear.

我們很難用肉眼看出近日點和遠日點太陽視直徑的變化，但在這張圖上顯而易見。

Slightly more solar energy is received when the Sun and Earth are closest (the perihelion) than when they are farthest apart (the aphelion).

太陽和地球的距離最近（近日點）時，所接收的太陽能要比距離最遠（遠日點）時接收的稍多一點。

But it's not that simple either, because the dates of the perihelion and aphelion are also shifting.

但這并不是簡單的一件事情，因為近日點和遠日點的日期都會變換。

perihelion, nearer the sun, than when it's at aphelion, its furthest

行星在離太陽很近的近日點飛行更快，在最遠距離的遠日點

axes less than 1. 0 AU and aphelion distances greater than 0. 983 AU;
