The “Cold Moon,” December’s supermoon and the last of 2025, brought a celestial spectacle to skywatchers worldwide on December 4 and 5. This phenomenon occurs when a full moon aligns with its perigee—the closest point to Earth in its orbit—making it appear up to 14% larger and 30% brighter than its more distant counterpart.
Astronomers recorded the peak at 7:14 a.m. Beijing Time on December 5, corresponding to December 4 evening across the Americas and night in Europe. The moon’s perigee distance hovered around 357,200 kilometers, offering a rare opportunity for stunning astrophotography and casual skywatching alike.
