Biggest Supermoon of 2025 Arrives in November
Experts announce that the full November supermoon, known as the "beaver moon," will be the largest and brightest moon of 2025. This event marks the second of three consecutive supermoons lighting the night sky this year.
Why It's Called the Beaver Moon
The November moon earns its nickname because it coincides with the period when beavers are actively preparing for winter.
Moon Phases and Visibility
- Tuesday night: Moon reaches 99% fullness during its waxing gibbous phase.
- Wednesday night: Moon is 100% full, at peak brightness.
- Thursday night: Moon dims slightly to 98% fullness in its waning gibbous phase.
What Makes This Moon a Supermoon
The moon's elliptical orbit around Earth, occurring every 27 to 28 days, means its distance varies at each full phase. When a full moon appears closer than usual, it is termed a supermoon due to its larger and brighter appearance.
"At its nearest point, the beaver moon will be 221,817 miles from Earth," the Old Farmer’s Almanac notes. "This is the closest supermoon of the year!"
Other 2025 Supermoons
The October 6 full moon was also a supermoon, and December 4 will see the third consecutive supermoon of 2025.
Author's summary: The November beaver moon will be the closest and brightest supermoon of 2025, marking the second in a series of three consecutive supermoons this year.
