If this is an ellipse around the Earth, this would be perigee and this would be apogee.
如果这是一个围绕地球的椭圆形，那么这是近地点，这是远地点。
This phenomenon is called "lunar perigee", or "SuperMoon".
这一现象被称为”月球近地点”或”超级月亮”。
If this is an ellipse around the Earth, then this would be perigee and this would be apogee.
如果这是一个围绕，地球的椭圆形轨道，那么这是近地点，这是远地点。
An anomalistic month refers to successive returns to perigee, a period of 27.55455 days.
一个近点月指的是返回到近地点相继的时间，为27.55455天。
Saturday night (Jan. 10) the moon will be at perigee, the closest point to us on this orbit.
星期六晚上（1月10日），月亮将会达到近地点，轨道上离我们最近的一点。
This phenomenon of extreme proximity, known as' maximal perigee, 'only occurs once every 18 years.
这种被称为“近地点”的月球最大程度接近地球的现象每十八年才发生一次。
Rising on March 19, its exact full phase occurred within an hour of perigee, the closest point in the Moon's orbit to Earth.
3月19日那天的月亮，它最圆的相位发生在月球运行到近地点(月球轨道距离地球最近)附近一个小时以内的时间内。
We know the period, we know where apogee is, we know where perigee is, - we know the orbital period — anything we want to know.
知道周期，知道远地点，和近地点在哪里，知道轨道周期-，知道了想知道的一切。
The average full moon at perigee appears around 12 percent larger than an average non-perigee full moon. Supermoons, even more so.
事实证明的确如此，于近地点观测到的满月要比非近地点观测到的大12%左右，超级月亮相对会更大一些。
Likewise, because the size of the moon's orbit varies slightly, each perigee is not always the same distance away from Earth.
同样，由于月亮轨道并不是一成不变，有轻微的变动，所以每次月球运行至近地点的位置与地球的间距是不一样的。
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AE D极轨卫星近地点的变化及其相应的大气膨胀和密度分布情况。
Seen here, the near perigee Full Moon still hugs the horizon, distorted by atmospheric refraction as it rises over Boston, Massachusetts, USA.
在上面这张照片中，这轮因大气折射而显得有些变形的超级满月，紧挨着地平线，就好像正在美国波士顿市上空冉冉升起。
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.
下一个看见这么又大又亮的满月的机会，将出现在明年的5月6日，而且它最圆的相位出现的时间只有近地点附近的数分钟而已。
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.
为了保证冻结轨道的冻结特性，平面内轨道控制需要对半长轴、偏心率和近地点幅角都控制。
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.
为了保证冻结轨道的冻结特性，平面内轨道控制需要对半长轴、偏心率和近地点幅角都控制。
