1·A comet is at aphelion when it is farthest from the sun.

彗星离太阳最远时就是在它的远日点上。

2·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？

3·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。

4·The point in the orbit nearest the sun is called perihelion, while the point farthest is called aphelion.

在轨道上最接近太阳的点被称为近日点，而最远离太阳的点被称为远日点。

5·W hen the Earth moves from perihelion to aphelion, its radiation belts are expansion, and aphelion to perihelion contraction.

当地球从远日点运动到近日点时，地球辐射带向内收缩。

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

他还指出了，地球在近日点的速度要比它在远日点快，近日点离太阳比较近，远日点是距离太阳最远的地方。

7·This composite neatly compares two pictures of the Sun taken with the same telescope and camera on the dates of Perihelion (closest approach) and Aphelion in 2008.

这张合成照片直观地比较了两张由同一台望远镜和照相机拍摄的太阳，一张拍摄于2008年近日点，另一个拍摄于同年的远日点。

远日点

1·The point in the orbit nearest the sun is called perihelion, while the point farthest is called aphelion.

在轨道上最接近太阳的点被称为近日点，而最远离太阳的点被称为远日点。

2·W hen the Earth moves from perihelion to aphelion, its radiation belts are expansion, and aphelion to perihelion contraction.

当地球从远日点运动到近日点时，地球辐射带向内收缩。
