FULL MOON DECEMBER 2025

 

(A Celestial Finale

Mark your calendars for a spectacular celestial event! December's Full Moon, traditionally known as the Cold Moon, will grace the sky as the final Supermoon of 2025. While the precise moment of maximum illumination occurs on Thursday, December 4, the Moon will appear full, large, and brilliantly bright for several nights, making it a perfect viewing opportunity for stargazers.

What is the Cold Moon?

The name "Cold Moon" originates from Native American, colonial American, and European traditions, aptly describing the time of year when winter's chill descends upon the Northern Hemisphere and the nights grow longer and colder. Other traditional names include the Long Night Moon, referring to its proximity to the Winter Solstice, which marks the longest night of the year.

🌑 What makes it a Supermoon? 

This Cold Moon is a 'Supermoon' because it coincides with the Moon reaching its perigee—the point in its elliptical orbit when it is closest to Earth. When the Full Moon phase occurs near perigee, it can appear up to 14% larger and nearly 30% brighter than an average Full Moon. This makes the final Full Moon of 2025 an especially dazzling sight.

The best time to witness its awe-inspiring size is often right after moonrise or just before moonset, when it is low on the horizon. At this time, the Moon Illusion—an optical effect where the Moon appears much bigger due to its proximity to foreground objects like trees and buildings—enhances its dramatic presence.
