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。
The Q is - do you mean Pluto in its aphelion or perihelion ?───的问题是，冥王星此时是在近地点还是远地点？
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。
In all this Cuban business there is one man stands out on the horizon of my memory like Mars at perihelion .───在所有与古巴有关的故事中，有一个人令我无法忘怀，他就像近日点的火星一样耀眼。
Dust trails laid down at various perihelion returns during the 19th century seem to have been responsible for the last two main outbursts.───奠定了在不同的近日点回报在19世纪的灰尘足迹似乎已经在过去的两个主要的爆发负责。
How much does the direction of perihelion change each orbit?───近日点方向使每个轨道改变了多少？
position of a planet as defined by its angular distance from its perihelion (as observed from the sun).───从太阳观察到的行星距近日点的角度偏差。
A comet is at perihelion when it is closest (=very close) to the sun.───彗星最接近太阳时，它就是在近日点。
Otherwise difficult to notice, the change in the Sun's apparent diameter between Perihelion and Aphelion is clear.───我们很难用肉眼看出近日点和远日点太阳视直径的变化，但在这张图上显而易见。
According to Marsden's calculations, this comet reaches its closest point to the Sun (perihelion) on March 18th.
This resonant condition permitted Mariner 10 to fly by Mercury at close range at the times of alternate perihelion passages.
If capital M were the Sun, we would call that "aphelion" and "perihelion."
When perigee and perihelion coincide tidal range is at its greatest.
How much does the direction of perihelion change each orbit?
Thus, at consecutive perihelion passages, opposite points on the equator pointed at the Sun.
W hen the Earth moves from perihelion to aphelion, its radiation belts are expansion, and aphelion to perihelion contraction.

So, the perihelion cannot be considered as a verification of Einstein's theory although it does suggest that his theory would be in the right direction.
