The figures
At 23:14 UTC on Thursday, December 4, 2025 the Moon reaches 13°04' Gemini with the Sun opposite at 13°04' Sagittarius. The Moon is 357,216 km away at that instant, 27,184 km inside the 384,400 km average, which is what makes this one a supermoon: the disc runs a few per cent wider and brighter than an ordinary full moon. The degree, 13°04' Gemini, places it in the second decan of Gemini, on the axis that runs across to Sagittarius. It is the 23rd of the 24 lunations dated for 2025, and the cycle it belongs to is set out in what a lunation is.

Why it is called the Cold Moon
The Cold Moon is the traditional North American and European name for the full Moon of December, and in 2025 it falls on December 4, 2025 at 13°04' Gemini. Those names follow the calendar month rather than the zodiac, which is why the 2025 one lands in Gemini at 13°04' Gemini while other years put it elsewhere.
