Cold Moon Supermoon Peaks Thursday Evening, Capping 2025’s Trio

The full moon occurs near perigee, producing a subtly larger, brighter disk with slightly higher tides.

Overview

  • Peak illumination is expected around 6:14–6:15 p.m. EST on Dec. 4, marking the year’s final supermoon.
  • At roughly 221,965 miles from Earth, the Moon will be near its closest approach during this full phase.
  • NASA estimates that supermoons can appear up to about 14% larger and 30% brighter than the faintest full moons.
  • The view is most striking just after moonrise because of the moon illusion, and no special equipment is needed.
  • The Cold Moon is the third consecutive supermoon of 2025, with another supermoon anticipated in January 2026.
