Now we want to know what the situation is with perigee and with apogee.───現在我們要看看，近地點和遠地點的情況。
The Moon reaches its absolute perigee once a year.───月球每年有一次達到它的絕對近地點。
If this is an ellipse around the Earth, this would be perigee and this would be apogee.───如果這是一個圍繞地球的橢圓形，那么這是近地點，這是遠地點。
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）。
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。
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”。
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。
This phenomenon of extreme proximity, known as 'maximal perigee, ' only occurs once every 18 years.───這種被稱為“近地點”的月球最大程度接近地球的現象每十八年才發生一次。
The average full moon at perigee appears around 12 percent larger than an average non-perigee full moon. Supermoons, even more so.───事實證明的確如此，于近地點觀測到的滿月要比非近地點觀測到的大12%左右，超級月亮相對會更大一些。
Consequently the force of gravity at perigee is not enough to hold it in a circular orbit.
The Moon reaches its absolute perigee once a year.
The time between two passages at the perigee ( of the Moon ).
This phenomenon of extreme proximity, known as 'maximal perigee, ' only occurs once every 18 years.
A spacecraft passing through its perigee point is moving faster than an equivalent craft on a circular orbit of the same radius.
This phenomenon is called "lunar perigee", or "SuperMoon".
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) .
He also stressed that the upcoming maximal perigee had nothing to do with the events in Japan.
The shape and perigee of artificial satellite orbits shall continually variate due to caused by the atmospherical drag and the earth gravity.
