CAIRO – 2 December 2017: People around the world will have one final opportunity to watch 2017’s first and last Supermoon on Sunday, December 3.
The December Supermoon will be 14 percent larger and 30 percent brighter than ordinary full moons, according to reports issued by National Geographic.
According to Space.com, “Supermoons happen when a full moon approximately coincides with the moon's perigee, or a point in its orbit at which it is closest to Earth. This makes the moon appear up to 14 percent larger and 30 percent brighter than usual.”
National Geographic also added, “The coming of winter earned December's full moon the name cold moon. Other names include the long night moon and the oak moon.”
