It’s official! With the arrival of the Christmas season, we are also approaching the end of another cycle and, consequently, the return of the cold season. However, before you say ‘goodbye’ to 2025, take the opportunity to contemplate the last Supermoon of the year, also known as the “Cold Moon”.
Set for December 4, the next Full Moon is very special, not only because it coincides with a Supermoon, but also because it will be the highest in the Northern Hemisphere and the lowest in the Southern Hemisphere until 2042. In other words, this phenomenon won’t be repeated for another 18 years.
According to the specialized website Star Walk, in the Northern Hemisphere the Full Moon will remain high for longer, which will make it easier to observe even in urban environments, between buildings and other structures. However, it should be borne in mind that weather conditions can interfere with viewing, if they are not the most favorable.

What is a Supermoon?
According to the same source mentioned above, the last Supermoon of 2025 will appear 7.9% larger and 15% brighter than an average Full Moon. But, there is a question that arises. What is a Supermoon anyway?
A Supermoon happens when a Full Moon coincides with perigee, the closest point of the Moon to Earth in its orbit,” reads Star Walk.

The origin of the name “Cold Moon”
As with other moons, to talk about the origin of the name “Cold Moon” you have to travel to the other side of the Atlantic, where the Native American tribes gave it different names depending on the time of year.
In this case, the December Full Moon is called the “Cold Moon” due to the low temperatures that are felt at this time; a nomenclature that is the responsibility of the Mohawk (indigenous people of North America).
