However, its motion around the Sun is faster at perihelion than aphelion.

然而，它在近日点比在远日点时公转更快。

The most distant point is known as aphelion and occurs around the 4th of July.

最远的点被称为“远日点”，大约出现在7月4日。

Meanwhile, it's at its slowest in early July, at its furthest point from the Sun, or aphelion.

同时，它在 7 月初最慢，在离太阳最远的点，或远日点。

The motion of Newton's comet at aphelion may be equally slight.

牛顿彗星在远日点的运动可能同样轻微。

At aphelion, Mercury's spin is a bit faster than its orbital speed, so the Sun moves rapidly westward across the sky.

于是在远日点时，水星的自转速度会比它的公转速度稍快一点，所以太阳会在天空中快速地向西移动。

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.

他还算出这个行星在距离太阳最近的近日点比在距离太阳最远的远日点时运动的速度快。

The tides from the Sun are far stronger on Mercury when it's at perihelion, the closest point in its orbit to the Sun, than when it's at aphelion, the farthest point in its orbit.

在近日点，也就是水星与太阳距离最近处，它受到的来自太阳的引潮力比在远日点(水星轨道上离太阳最远的点)时要强烈得多。

The corresponding change in gravitational force causes the Earth to move fastest in January when it reaches its closest point to the Sun, the perihelion, and the slowest in July when it reaches its farthest point, the aphelion.

相应的地球引力的变化使地球在一月时公转更快，也就是到达离太阳最近的点时，这个点被称作“近日点”，到达离太阳最远的点时，公转最慢，这个点也被称作“远日点”。

Tracing the Winchcombe meteorite's path from the pictures taken of its arrival showed its orbital aphelion (the point in that orbit farthest from the Sun) to be just inside the orbit of Jupiter.

从 Winchcombe 陨石到达时拍摄的照片追踪它的路径显示它的轨道远日点（该轨道中离太阳最远的点）正好在木星轨道内。
