The final full supermoon of 2025, called the Cold Moon, lit up the skies across the United States on December 4 local time (early December 5 IST), marking a brilliant conclusion to this year’s lunar display. Peak illumination occurred around 6:14–6:15 pm EST (4:44–4:45 am IST, December 5), according to the U.S. Naval Observatory.

The Cold Moon, the third and last supermoon of the year, reached a perigee distance of roughly 221,965 miles from Earth, making it appear slightly larger and up to 30% brighter than a typical full moon. Clear late-autumn weather across many regions of the US enhanced the viewing experience. An optical effect known as the “moon illusion” made the rising moon appear even bigger, particularly striking on the horizon.
