AccuWeather says that the last supermoon of the year will fall on Dec. 14, the final in a trio of super moons that appeared the fall. A supermoon happens when the moon is on the perigee side of the Earth's obit, putting it closer to our planet and causing the satellite to look much bigger and brighter.
This last supermoon, though, will occur at the same time of the Geminid meteor shower, which will fade out most of the meteor's visibility during the peak, according to AccuWeather.
