There's a Supermoon this week! 🌕 The last full moon of 2025 is December’s Cold Moon. | AccuWeather

On 4 December 2025, the world will witness the Super Cold Moon, a rare full moon that occurs when the moon reaches its closest point to Earth. This alignment makes the moon appear dramatically larger, clearer, and brighter than a normal full moon—creating one of the most spectacular natural sky events of 2025. • The moon will be at perigee, only about 357,000 km from Earth, amplifying its size and brightness • It will shine nearly 30% brighter and appear 14% larger due to the reduced distance •
