In the night from 13 to 14 November, the Moon in full phase will approach closest to Earth over the past 60 years.
The phenomenon of “supermoon” happens when the full moon approaching very close to Earth’s orbit once in a few decades.
Note that in the night from 13 to 14 November, the Moon will pass by earth at a distance of 356 thousand kilometers, which is the closest distance since 1948.
A supermoon is 30% more brighter and 30%, and the diameter is more by 14% than usual.
The moon itself is always moving around the Earth in the form of an ellipse, so there are times when she are coming to the surface close. The supermoon phenomenon occurs when at the time of its closest pass of Earth the Moon is full.
The reason for this phenomenon is that the form of the ellipse which the Moon passes around the Earth, changing all the time due to gravitational forces. When the phenomenon the supermoon coincides with a strong elongation of the ellipse, the Moon becomes bigger and brighter, because of its full phase as close passes by Earth.
