The Q is - do you mean Pluto in its aphelion or perihelion ?

我的问题是，冥王星此时是在近地点还是远地点？

This means that the Earth moves faster along the orbit in winter near perihelion.

这意味着地球在靠近冬至点附近的冬季运行得较快。

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

但这并不是简单的一件事情，因为近日点和远日点的日期都会变换。
