  Have you ever gazed at the night sky and felt as though the Moon loomed larger than usual? Your eyes were not deceiving you. The Moon’s apparent size can __1__ subtly depending on where it is in its orbit. On certain occasions, it reaches its fullest phase while at its closest point to Earth. When these two events __2__, scientists and the public refer to the spectacle as a “supermoon.”

  The Moon does not orbit our planet in a perfect circle. Instead, it travels along a more oval-shaped __3__, completing one full orbit every 27 days. Consequently, there are times when it __4__ its nearest point to Earth — about 363,300 km at perigee — and times when it lies at its farthest point, or apogee, about 405,500 km away. These distances vary slightly from one orbit to another, depending on the __5__ of the Sun and Earth. At perigee, the Moon can appear up to 14% larger and about 30% brighter than at apogee. If a full moon happens to take place at this point, the sight of such a large and bright __6__ in the sky is hard to miss.

  Though striking, supermoons are fairly common __7__, happening three to four times each year and always in succession. In other words, they may be observed in __8__ months.

  While its brilliance may capture our gaze, a supermoon’s impact on Earth is __9__. One of its most noticeable effects is the production of slightly higher tides than usual. Some observational studies have also suggested a slight increase in nighttime traffic accidents during these events, possibly because the Moon’s heightened brightness may __10__ drivers or slightly alter depth perception. If you want to enjoy the supermoon, be sure to catch the view from a safe place, just in case.

  你是否曾在凝望夜空時，感覺月亮比平常更大？你並沒有看錯。月亮的視覺大小會依據它在軌道中的位置而有細微的改變。在某些時候，它同時達到最圓的滿月階段且位於最靠近地球的位置。當這兩個事件同時發生時，科學家和大眾稱此奇觀為「超級月亮」。

  月球繞著地球運行的軌道並不是一個完美的圓。相反地，它沿著一條比較橢圓形的路徑運行，每二十七天完成一次完整的繞行。因此，有些時候它會到達距離地球最近的位置——約三十六萬三千三百公里處的近地點。而有些時候則位於最遠的位置——也就是約四十萬五千五百公里處的遠地點。這些距離會因每一次的繞行軌道不同而略有差異，取決於太陽和地球的位置。在近地點時，月球看起來可能會比在遠地點時大14%，亮度提高約30%。如果剛好在這個時候出現滿月，那麼天空中如此巨大而明亮的圓盤狀物體是很難忽視的。

  雖然壯觀，但超級月亮是滿常發生的事件，每年會發生三到四次，且總是連續出現。換句話說，可能可以連續幾個月觀測到超級月亮。

  雖然它的光輝可能會吸引我們的目光，但超級月亮對地球的影響有限。它最明顯的影響之一就是會造成比平常稍高的潮汐。一些觀測研究也指出，在這些時期，夜間交通事故略有增加，可能是因為月球提高的亮度會分散駕駛的注意力，或是稍稍改變了深度知覺。如果你想欣賞超級月亮，務必要在安全的地方觀賞這幅美景，以防萬一。
