According to the “space” website, the four main phases of the moon (new moon, first quarter, full moon, last quarter) occur approximately one week apart, and the full moon phase is the most beautiful and attractive among them.
The next phase of the moon will be the third quarter or last quarter, where the moon begins to diminish from its full moon shape to a half-moon, and this will occur specifically on December 11th.
As for why the moon appears full until now, NASA explained that the moon remains looking like a full moon for a few days before and after reaching the actual full phase. The average observer can see the moon full for a few days before and after the actual date.
The full moon in December coincided with its approach to within 10% of its closest point to Earth in its elliptical orbit, resulting in a beautiful “supermoon.” (اليوم السابع)
