Cold Supermoon Lights Up December Skies
Clear Facts
- The Cold Supermoon, the last full moon of 2025, reaches peak fullness on the morning of December 4.
- North Americans will see the moon appear largest and brightest Friday evening as it rises at sunset.
- This Supermoon will be just 221,813 miles from Earth at its fullest, making it look larger than usual.
Stargazers in the United States should look toward the eastern horizon Friday at sunset for the best view of the year’s final full moon.
The name
“Cold Moon”
comes from the deep winter chill that settles on the Northern Hemisphere this time of year.
Supermoons occur when a full moon coincides with its closest approach to Earth, making it noticeably brighter and bigger in the sky.
This marks the third Supermoon in a row for December, with all three appearing early in the month, a typical pattern for these celestial events.
The Cold Supermoon ends the trio for 2025, providing an opportunity for Americans to witness a striking natural spectacle that celebrates the wonders of creation.
