Bigger Than Usual: What to Know About the Cold Supermoon

Get ready for a spectacular view in the night sky as the Cold Supermoon, the second-largest full moon of 2025, takes center stage. This December 4 full moon appears bigger and brighter than usual due to its higher position in the night sky and proximity to Earth. The Cold Supermoon, also known as the December full moon, rises within the constellation Taurus and is most visually impressive at the time of moonrise. The Cold Supermoon is the third of four supermoons in a row and the second-largest of the year, following the Beaver Moon in November. Supermoons are typically 10% larger than average. This phenomenon has sparked interest among sky-watchers, with some sharing photos and reactions online. Indigenous people of the US have their own names for the December full moon, including the Frost Exploding Trees Moon, Moon of the Popping Trees, and Winter Maker Moon. NASA has shared photos of the Cold Supermoon, reminding sky-watchers to 'look up at the Moon' and appreciate the last full moon of 2025. The Cold Supermoon will continue to be visible on December 5, rising an hour or so after sunset. As a supermoon, it promises to be an impressive sight, and its proximity to Earth makes it a great opportunity for stargazers to observe the night sky.
