Rare Supermoon Lights Night Sky, Closest and Brightest Since 2006

Astronomers say a comparable alignment is not expected until 2042.

Overview

  • The full Moon reached perigee on the night of December 4–5 and was widely observed worldwide, with striking views reported in Provence.
  • At its closest, the Moon was about 356,000 kilometers from Earth, compared with an average distance of roughly 384,000 kilometers, according to the Observatoire de Paris.
  • Multiple reports put the apparent change at about 8% larger and around 15% brighter than a typical full Moon, though one outlet cited a higher brightness estimate.
  • Scientists and outlets described it as the most impressive supermoon in 19 years, with the previous comparable event in December 2006.
  • Forecasts note other supermoons will occur before then, including one in January 2026, but they are not expected to match this event's intensity, and clouds limited viewing in parts of southwest France.
