And if we look at the Sun-Earth system from afar we find that the Earth's axis maintains the same orientation regardless of its position in its orbit around the Sun.

如果我们从远处看下与地球关系，我们可以发现地球自转轴始终保持相同方向，无论它在轨道位置哪地点。

But you're also maintaining composure to protect your lane and your position.

但你也要保持冷静来保护你滑行轨道和位置。

An annular eclipse is a solar eclipse that occurs when the Earth's orbit brings it relatively close to the sun at the same time that the moon's orbit takes it relatively far from the Earth.

日环食是日食种，指当地球在相对接近轨道位置，而与此同时月球在相对远离地球轨道位置，就会发生日环食。

The thickness of the track ballast usually ranges between 25-30 cm and varies depending on certain conditions pertaining to the geographical location of the railway track.

轨道道砟厚度通常在25-30厘米之间，并根据铁路轨道地位置某些条件而变化。

The newly launched final satellite of China's Beidou Navigation System has reached a fixed position in its operational orbit.

中国北斗导航系统新发射最后颗卫星已在其运行轨道上到达固定位置。

It took about a month to reach its orbiting position about 1.6 million kilometers away from Earth.

它花了大月时间到达距离地球160万公里轨道位置。

It got to around where Mars orbits today before a newborn Saturn reined it in.

它差不多到达了今天火星轨道位置，然后新生土星将其束住了。

It cares about where you are in this orbit about the sun.

它关心你在轨道上位置。

As asteroids on either side of this band orbit the sun, they pass Jupiter and get a little extra gravitational pull, but that pull comes at a different place with each orbit, so it kind of just averages out over time.

当这条带两侧小行星绕运行时，它们会经过木星并获得点额外引力， 但这种引力在每轨道上位置不同， 所以它会随着时间推移而平均化。

Both the tracking of the orbit of Uranus as well as the reconstruction of the orbit of Uranus immediately revealed that it was not following the orbit that it was supposed to, right?

对天王星轨道追踪以及对其轨道重建立刻表明， 它并未按照应有轨道运行，对吧？ 预测轨道与其实际位置出现了偏离。

When launched in 2021, it will take up a tight orbit around L2, Lagrange Point 2, a location 1.5 million kilometres, one million miles, beyond Earth's orbit away from the Sun.

2021年发射后， 它将进入L2（拉格朗日点2）周围紧密轨道，该位置位于地球轨道外侧150万公里（即100万英里）， 远离。

So when we rotate the wiper, the position where the wiper contacts the track changes, and thus changes the effective length of the resistive material that electricity flows through.

所以当我们旋转电刷时， 电刷接触轨道位置会发生变化，从而改变电流流经电阻材料有效长度。

With  the launch window for that comet missed, a new target had to be chosen, and ESA settled  on 67P due to the ideal position in its orbit.

由于错过了那颗彗星发射窗口，必须选择新目标， 欧洲航天局最终选定了67P， 因其轨道位置极为想。

And we see different amounts of that lit up side depending on where the moon is in its orbit around the sun.

我们看到被照亮那面大小，取决于月亮在其围绕轨道上位置。

They were actually being held in place in their orbit by a force emanating from the object they were orbiting.

实际上，它们之所以能在轨道上保持位置，是因为受到种源自其环绕天体力作用。

Some researchers are now starting to compile a massive data set that includes the best possible information on where everything is in orbit.

些研究人员现在开始编制庞大数据集，其中包括有关所有物体在轨道上位置最佳信息。

The wiper contacts the track in different locations than before, thus changing the distance along which the electricity passes through the resistive track, thereby changing the overall resistance.

电刷与轨道接触位置与之前不同，从而改变了电流通过电阻轨道距离，进而改变了整体电阻。

His work led to the discovery of positions with stable orbits for a small body orbiting two larger ones, now called Lagrange points.

他研究成果揭示了小天体围绕两大天体运行时， 存在稳定轨道特定位置，这些位置如今被称为拉格朗日点。

Janus,   the moon that contributes to the resonance, switches orbital positions every four years  with its close neighbour moon, Epimetheus.

雅努斯（Janus）是负责共振卫星，每四年与它近邻卫星埃庇米修斯（Epimetheus）交换轨道位置。

By continuously capturing images of the moon's surface as it descends, the  spacecraft is able to locate itself in real-time on orbital maps made by data from  other lunar rovers, including NASA's LRO, India's Chandrayaan-2, and Japan's SELENE.

通过在下降过程中持续捕捉月球表面图像，该航天器能够根据来自其他月球探测器数据，包括美国宇航局月球勘测轨道飞行器（LRO）、印度月船二号（Chandrayaan-2）以及日本月亮女神（SELENE），实时定位自己在轨道地图上位置。
