Quick Scoop

  • The last supermoon was on 4 December 2025, when the full Cold Moon lined up with one of the Moon’s closest approaches to Earth, making it appear slightly larger and brighter than an average full moon.
  • It was the third supermoon in a late‑year trio, following supermoons in October and November 2025.
  • Astronomers classify a supermoon when a full moon occurs near perigee (its closest orbital point to Earth), which can make it appear up to about 14% larger and around 30% brighter than the smallest full moon.
