Tonight’s moon – in front of the constellation Libra – arcs across the south throughout the night. Andrew asked, What determines if the moon will appear in the northern, southern, eastern, western sky?
在天秤座之前，今晚的月亮呈弧形状往南贯穿整个夜晚。安德鲁问，如果月亮出现在上空北边，南边，东边，西边是由什么来决定的？
First of all, Andrew, as seen from the northern temperate latitudes, the moon never appears due north. Instead, the moon follows more or less the same path that the sun does each day. You know how the sun shines in your south windows, but not your north windows? Likewise, you’ll never be kept awake by a moon shining low and due north … unless you travel to the southern hemisphere!
首先，安德鲁从北纬温带来看，月亮从来没有出现在正北。相反，月亮每天随着同一个条太阳每天运作的路径运转。你知道太阳如何照射在你南边的窗户上，儿不是你北边的窗户上？同样的，由于月光的低照，你也绝不会保持清醒。。。。。。除非你在南半球。
Otherwise … the moon is generally eastward (east, southeast, northeast) soon after it rises (just as the sun is). The moon appears in the south when highest in the sky (also like the sun). And (like the sun) the moon sets generally westward (west, southwest, northwest).
否则，月亮一般向东（东，东南，东北）运行，很快它就上升（正如太阳一样）。当出现在天空中的最高点（也像太阳一样）月亮这个时候就出现在南边。(跟太阳一样)月亮一般向西边（西边，西南，西北）落下。
So where you see the moon in the sky depends on how close it is to rising or setting. How can you know what time to expect moonrise or moonset? On average, as it pursues its monthly orbit around Earth, the moon rises 50 minutes later each day. I’m fond of this custom sunrise/sunset chart that also includes moon phases, and the rising and setting times of the moon.
因此不管你在天空中的哪边看到月亮都取决于它是何时起落。你是如何知道何时期盼月起月落的？平均的，月亮每天上升50分钟后，它就每月环绕着地球运转。我喜欢这样的月升月落现象，它也包括月亮月升月落阶段。

地理学得不行，其中有些地方不明白
