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

它花了大约一个月的时间到地球约160万公里的道位。

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的滑行道和位。

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

它关心你在太阳道上的位。

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的最后一颗卫星已在其运行道上到固定位。

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

雅努斯（Janus）是负责共振的卫星，每四年与它的近邻卫星埃庇米修斯（Epimetheus）交换道位。

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

一些研究人员现在开始编制一个庞大的数据集，其中包括有关所有物体在道上的位的最佳信息。

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.

道道砟的厚度通常在25-30厘米之间，并根据铁路道的地理位的某些条件而变化。

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.

如果我们从远处看一下太阳与地球的关系，我们可以发现地球的自转轴始终保持相同的方向，无论它在道位的哪一个地点。

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.

日环食是日食的一种，指当地球在相对接近太阳的道位，而与此同时月球在相对远地球的道位，就会发生日环食。

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.

当这条带两侧的小行星绕太阳运行时，它们会经过木星并获得一点额外的引力， 但这种引力在每个道上的位不同， 所以它会随着时间的推移而平均化。
