The night sky is a kind of quiet magic show for those willing to look up and pay attention. Every so often, the cosmos reminds us that we’re part of something far bigger than our day-to‑day pace. As the air turns crisper and the nights stretch longer, the very last full moon of the year prepares to take center‑stage.
This week, the sky is giving us our last and well deserved final lunar gift: the December full moon, affectionately known as the “Cold Moon,” will reach its peak on December 4, 2025, as CNET explains. The full moon in December is commonly called the Cold Moon, since it usually rises when temperatures begin to drop.
But this moon is not only special because it’s the last in 2025, but it also happens to be what we often call a “supermoon”, due to its proximity to Earth. This means it will showcase more luminosity and a subtly larger disc, visible right after the sun sets.
NASA explains that a supermoon appears about 14% larger and 33% brighter than a micromoon, which happens when the full moon is at its farthest distance from Earth, a point called apogee.
On the night of December 4th, check out the weather and make sure there are no clouds blocking your view, step outside (ideally climb to a rooftop or drive to a dark spot with little to no light pollution), and look up for the last full moon of 2025!
