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

然而，它在近日比在远日时公转更快。

Aphelion is the farthest orbital point from the sun and perihelion is the closest.

Aphelion（远日）太阳最远的轨道，而Perihelion（近日）指最近的。

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

最远的被称为“远日”，大约出现在74日。

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

同时，它在 7 初最慢，在太阳最远的，或远日。

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

星在远日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.

于在远日时，水星的自转速度会比它的公转速度稍快一，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太阳最近的近日比在距太阳最远的远日时运动的速度快。

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，也就水星与太阳距最近处，它受到的来自太阳的引潮力比在远日(水星轨道上太阳最远的)时要强烈得多。

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（该轨道中太阳最远的）正好在木星轨道内。

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时公转更快，也就到达太阳最近的时，这个被称作“近日”，到达太阳最远的时，公转最慢，这个也被称作“远日”。
