December 2025 cold supermoon: Tonight's full moon will be a spectacular sky-watching finale. Here's how to see it
"December's moon is called the cold moon because of the chilly winter temperatures. According to EarthSky, it is also known as Moon Before Yule or the Long Night Moon. The moon orbits Earth in an elliptical pattern, which means the orb has differing proximity to the planet."
"Endings are tricky: You want closure and to go out with a bang-which is a hard balance. It's natural to want the end of the year to be meaningful. Even the moon appears to agree with this sentiment, and it's about to prove it. The final full moon of 2025, which is also called the cold moon, will be a bright supermoon occurring on December 4."
December's full moon is called the cold moon because of chilly winter temperatures and is also known as Moon Before Yule or the Long Night Moon. A supermoon occurs when a full moon aligns with perigee, the moon's closest approach to Earth, making the moon appear brighter and fuller. The December 4, 2025 event is the finale of three consecutive supermoons and will be the highest-hanging full moon of 2025. The year included 12 full moons, three supermoons and two total lunar eclipses. The most dramatic viewing time is just after moonrise due to the moon illusion, when the moon appears larger near the horizon.
