微月与超级月亮之比较

说明: 上周三的超级月亮有什么特别之处？上周，出现了一轮比平常更大更亮的满月。这是因为月球的满月阶段恰好发生在距离近地点不久的时候——即月球在其椭圆轨道上距离地球最近的位置。虽然超级月亮的具体定义精确条件因情况而异，但上周三的超级月亮无疑是今年距离地球最近、最大、最亮的满月。超级月亮受欢迎的原因之一是它们非常容易观察——只需在日落时走到户外，就能欣赏到令人叹为观止的满月升起！这里的图片中，上周三的超级月亮与四月的微月相比较——微月是指当满月发生在月球轨道的最远处附近，它看起来会比平常稍小且更暗。根据不同的定义，每年至少会出现一次超级月亮，下个月（moon-th）还会有一次。

英文原文:
Explanation: What was so super about Wednesday’s supermoon? Last week, a full moon occurred that appeared slightly larger and brighter than usual. The reason is that the Moon’s fully illuminated phase occurred within a short time from perigee – when the Moon was its closest to the Earth in its elliptical orbit. Although the precise conditions that define a supermoon vary, last Wednesday’s supermoon was surely the closest, largest, and brightest full moon this year. One reason supermoon s are popular is because they are so easy to see — just go outside at sunset and watch an impressive full moon rise! Pictured here, Wednesday’s supermoon is compared to April’s micro moon — when a full Moon occurs near the furthest part of the Moon’s orbit — so that it appears slightly smaller and dimmer than usual. Given many definitions, at least one supermoon occurs each year, with another one coming next month (moon-th).
