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

然而，它在近日比在日时公转更快。

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

最被称为“日”，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，或日。

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

星在日运动可能同样轻微。

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

于是在日时，水星自转速度会比它公转速度稍快一，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离太阳最近近日比在距离太阳最日时运动速度快。

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，也就是水星与太阳距离最近处，它受到来自太阳引潮力比在日(水星轨道上离太阳最)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.

相应地球引力变化使地球在一月时公转更快，也就是到达离太阳最近时，这个被称作“近日”，到达离太阳最时，公转最慢，这个也被称作“日”。

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 陨石到达时拍摄照片追踪它路径显示它轨道日（该轨道中离太阳最）正好在木星轨道内。
