Cold Moon 2025: Final Supermoon of the Year
The Cold Moon is the last supermoon of 2025, happening on December 4.
It's called a supermoon because it's closer to Earth, making it look bigger and brighter.
The best time to see it is just after it rises, when it looks even larger due to an illusion.
This moon is special because it's the last one of the year, and it's also the highest full moon in the Northern Hemisphere sky for 2025.
You don't need special equipment to see it, but binoculars can help you see more details.
The moon's closeness also makes tides a bit stronger.
A lunar year is shorter than a solar year, so sometimes we get 13 full moons in a year, like in 2023 and again in 2028.
The Cold Moon, the final supermoon of 2025, will rise on December 4.
It will appear larger and brighter due to its proximity to Earth, known as a supermoon.
The best viewing time is just after moonrise, when the 'moon illusion' makes it look even bigger.
The Cold Moon is also the highest full moon in the Northern Hemisphere sky for 2025.
The moon's closeness will slightly intensify tides and can be viewed with or without binoculars.
