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). 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[2]的满月阶段[3]恰好发生在距离近地点[4]不久的时候——即月球在其椭圆轨道[5]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[6]无疑是今年距离地球最近、最大、最亮的满月[7]。 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[8]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[9]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[10]在月球轨道的最远处附近,它看起来会比平常稍小且更暗[11]。根据不同的定义,每年至少会出现一次超级月亮[12],下个月(moon-th)还会有一次。
