Why is it called Cold Moon?
People gave the December full moon the name Cold Moon because this month feels colder in many parts of the world. The name connects to winter air and long nights. Some groups also feel the name has cultural meaning from older traditions. NASA explains that “at closest approach, a supermoon can appear about 14% larger than the faintest full moon.
It can also shine roughly 30% brighter.” This change happens because the moon moves in an oval path. Every year the sky gets around three or four of these bigger moons, and they often look different enough to notice with just your eyes.
