The figures
At 22:47 UTC on Thursday, December 20, 2029 the Moon reaches 29°21' Gemini with the Sun opposite at 29°21' Sagittarius. The distance is 398,122 km, 13,722 km further out than the 384,400 km average — near enough to the mean that the apparent size is unremarkable. The degree, 29°21' Gemini, places it in the third decan of Gemini, on the axis that runs across to Sagittarius. This one is also a total lunar eclipse, so the Moon is within range of a node at 29°21' Gemini rather than merely opposite the Sun. It is the 24th of the 24 lunations dated for 2029, 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 2029 it falls on December 20, 2029 at 29°21' Gemini. Those names follow the calendar month rather than the zodiac, which is why the 2029 one lands in Gemini at 29°21' Gemini while other years put it elsewhere.
