Witness the Last Supermoon of the Year: How to See the Cold Moon on Thursday
A cold supermoon, known as the Cold Moon, is set to illuminate the night sky on December 4, 2025. This event marks the final full moon of the year and is one of the last celestial spectacles of the year. Being a supermoon, it will be an impressive sight for skywatchers.
What Is a Supermoon?
A supermoon occurs when the full moon is at perigee, the closest point in its orbit to Earth. The moon’s elliptical orbit brings it between approximately 380,000 kilometers at perigee and 407,000 kilometers at apogee. For this supermoon, the distance will be about 357,000 kilometers from Earth, making it the second-closest full moon of 2025.
Significance of the Cold Moon
- This full moon is the last of 12 full moons in 2025.
- It will rise high in the sky, especially as the winter solstice approaches on December 21.
- The full moon will appear roughly 8 percent larger and up to 16 percent brighter than a regular full moon.
Viewing Details
Skywatchers should prepare to see this celestial event at its peak when it reaches full illumination at 6:14 PM ET on December 4. Although it may appear full on the night before and after, the optimal viewing will occur during its peak. The phenomenon known as lunar illusion can also be observed at moonrise, creating the optical effect of a larger moon.
Tips for Optimal Viewing
- Find a location with an unobstructed view of the eastern horizon.
- Consider observing from an elevated position, such as a hill or meadow.
- Check weather conditions to ensure clear skies for the best experience.
Don’t miss this opportunity to enjoy one of the year’s most remarkable lunar events with the Cold Moon, the third consecutive supermoon of the year.
