Closest Full Moon of 2025 Rises Nov. 5, Delivering a Subtle ‘Supermoon

A near‑perigee alignment called perigee‑syzygy produces a small size and brightness boost that the horizon illusion often exaggerates.

Overview

  • The Moon reaches full phase on November 5 at 14:19 UTC and its minimum distance of about 356,834 kilometers at 23:16 UTC, making it the closest full moon of the year.
  • Compared with an average full moon, the disk will appear roughly 7–14% larger and up to about 30% brighter, according to figures cited from NASA and Time and Date.
  • Astronomers prefer the term perigee‑syzygy, while the popular label “supermoon” lacks a formal definition and originated outside scientific usage.
  • Experts note that the striking size at moonrise stems largely from the moon illusion, as foreground cues near the horizon make the disk seem unusually big.
  • Viewing is best at moonrise from a clear vantage point using foreground elements or a mild telephoto lens, though forecasters expect patchy clouds and fog in parts of Germany and caution that detailed conditions may change.
