You now have the ecliptic longitude of perigee of the sun for the mean summer solstice of your chosen year (and effectively for the entire year).(你現在有黃道經度的近地點的陽光平均夏季冬至，你選擇了一年(而有效地為整個一年)。)

In this paper, variations of AE-D's perigee altitudes, the corresponding atmospheric expansion and the density distributions are analyzed.(本文分析了AED極軌衛星近地點的變化及其相應的大氣膨脹和密度分布情況。)

If you managed to miss this perigee Full Moon, make a note on your calendar.(如果你真得錯過了這輪近地滿月，在你的日歷上做個記號。)

Since the average lunar perigee is 364,397 km (226,432 mi), on March 19 the moon was about 7,820 km (4,860 mi) closer to the earth.(由于月球表面距地球的平均近地點距離約為364,397KM(26432米)。19日晚的超級月亮距地球的距離在此平均值的基礎上又縮短了近7820KM(4860米)。)

Likewise, because the size of the moon's orbit varies slightly, each perigee is not always the same distance away from Earth.(同樣，由于月亮軌道并不是一成不變，有輕微的變動，所以每次月球運行至近地點的位置與地球的間距是不一樣的。)

In order to guarantee the characteristics of frozen orbit, in-plane orbit control needs to adjust the semi-major axis, eccentricity, argument of perigee simultaneously.(為了保證凍結軌道的凍結特性，平面內軌道控制需要對半長軸、偏心率和近地點幅角都控制。)

Your next chance to see the Moon this large and bright, this time at full phase within only a few minutes of lunar perigee, will be next year on May 6.(下一個看見這么又大又亮的滿月的機會，將出現在明年的5月6日，而且它最圓的相位出現的時間只有近地點附近的數分鐘而已。)

Scientists call these perigean tides, because the moon'sclosest point to Earth is called perigee.(科學家們稱月球離地球比來的點為近地址，這種潮水為“近月潮”；)

This phenomenon is called "lunar perigee", or "SuperMoon".(這一現象被稱為”月球近地點”或”超級月亮”。)

The time between two passages at the perigee ( of the Moon ).(月球連續兩次經過近地點所需的時間。)
