Overview
- The full phase occurs at 00:14 MEZ on December 5, capping a run of three consecutive Supermoons this autumn.
- At roughly 357,217 kilometers from Earth, the Moon is near perigee, appearing up to about 14% larger and 30% brighter than distant full moons, though the difference is modest to the eye.
- The most dramatic views come shortly after moonrise on December 4 and 5 when the horizon setting amplifies the impression through the well-known moon illusion.
- Observers can look for the Pleiades and Uranus close to the Moon, Jupiter rising below it after about 19:00, and Saturn visible earlier in the southern sky.
- Looking ahead, outlets report only one Supermoon in 2026 on December 24, and some guides note this December full Moon rides unusually high in the Northern Hemisphere with projections of a comparable height not returning until 2042.
