Overview of the Event
The final supermoon of 2025, known as the Cold Moon, reached its peak illumination on December 4 at 6:14 p.m. ET. This event marked the third consecutive supermoon of the year, following the Hunter's Moon in October and the Beaver Moon in November. The Cold Moon is characterized by its proximity to Earth, making it appear larger and brighter than a typical full moon.
What is a Supermoon?
A supermoon occurs when a full moon coincides with the moon's closest approach to Earth, known as perigee. During this event, the moon can appear up to 14% larger and 30% brighter than when it is at its farthest point, or apogee. The Cold Moon, specifically, is named for the frigid temperatures typical of December, and it is also referred to as the Long Night Moon, reflecting the extended nights leading up to the winter solstice.
Viewing Conditions and Timing
Skywatchers were advised to look for the Cold Moon shortly after sunset, as it rises in the eastern sky. The moon's peak visibility occurs around moonrise, when it can appear particularly large due to an optical illusion known as the "moon illusion." This effect makes the moon seem larger when it is near the horizon compared to when it is high in the sky. In many regions, including parts of the United States, clear skies were predicted, providing optimal viewing conditions.
Historical Context
The Cold Moon is part of a series of supermoons that have occurred in 2025. This year featured three supermoons in a row, a rare occurrence that has drawn significant attention from astronomy enthusiasts. The next supermoon, the Wolf Moon, is scheduled for January 3, 2026, continuing the celestial spectacle into the new year.
Official Statements & Responses
NASA and various meteorological organizations highlighted the significance of the Cold Moon, noting its brightness and visibility. "The brightness of these supermoons in the winter, especially when it’s really cold, can be enhanced because the trees aren’t blocking the light," stated Noah Petro, project scientist for NASA’s Artemis III mission.
Criticism & Opposition
While the event was celebrated, some regions faced challenges due to weather conditions. For instance, parts of Michigan and Tennessee reported cloudy skies that could obstruct the view of the supermoon. Critics noted that despite the excitement surrounding the supermoon, local weather could dampen the experience for many observers.
What's Next?
Following the Cold Moon, the next full moon will be the Wolf Moon on January 3, 2026. This will be the fourth consecutive supermoon in the current series, and it is expected to attract similar interest from the public and astronomy enthusiasts alike.
Conclusion
The December 2025 Cold Supermoon provided a stunning visual display, marking the end of the year with a celestial highlight. As skywatchers looked forward to the Wolf Moon in January, the Cold Moon served as a reminder of the beauty and wonder of astronomical events.
