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。
Mistakenly believe that doing elliptical motion of the satellite perigee and apogee of the orbit radius of curvature different.
