The Full Moon occurs this Wednesday, November 5, 2025, marking the biggest Supermoon of the year. The phenomenon occurs when the full phase coincides with perigee, the closest point to Earth in the lunar elliptical orbit. On this date, the satellite is approximately 356 thousand kilometers from the planet.
The event results in an appearance 7.9% larger and 16% brighter than an average full Moon. Proximity causes higher tides, an effect linked to the perigee and not the lunar phase. Night observers around the world can record the phenomenon.
- Distance at perigee: approximately 356 thousand km
- Distance at peak: more than 406 thousand km
- Orbital difference: about 50 thousand km
- Visual increase: up to 14% in size
Elliptical orbit explains variation in lunar size
The Moon’s trajectory around the Earth follows an elliptical shape, not a circular one. This characteristic causes variable distances between 356 thousand and 406 thousand kilometers. Perigee occurs nine hours after the flood phase in November.
Astronomers define a Supermoon as a full Moon within 90% of perigee. The term popularizes astronomy, despite astrological origins. Experts highlight that the difference is not always noticeable to the naked eye.
Traditional names mark the November full moon
The November Moon is called Beaver Moon in North American tradition. The name refers to the period when beavers built dams or collected fur for the winter. In 2025, it will take on the title Hunter Moon to succeed October’s Harvest Moon.
- Beaver Moon: animal preparation for winter
- Hunter Moon: night hunting after harvesting
- Other names: White Moon (China), Snow Moon (Wicca)
Best conditions for observing the Supermoon
Moonrise at dusk offers optimal vision. Closer to the horizon, it appears larger due to optical illusion. Atmospheric refraction gives the satellite an orange hue.
Observation requires clear skies and locations with low light pollution. Binoculars or telescopes magnify details of the lunar surface. The phenomenon occurs globally, regardless of hemisphere.
Sequence of Supermoons closes 2025 calendar
Three Supermoons mark the second half of the year. October sees Harvest Moon, November brings Beaver Moon and December ends with Cold Moon. Orbital proximity varies with each event.
The lunar orbit completes its cycle in 27.3 days. Full phases align with perigee at irregular intervalsares. 2025 events surpass annual averages in proximity.
Gravitational effects influence coastal tides
The closer approach intensifies gravitational force on oceans. Tides reach levels above standard. Phenomenon affects coastal regions across the planet.
Authorities monitor variations in ports and beaches. Historical data records elevations of up to 30 centimeters. Effect lasts for a few hours centered on perigee.
November’s Supermoon represents the second event of its kind in 2025. The first occurred in October with the Harvest Moon. The sequence highlights annual orbital variation. Observers record images at global tourist attractions. The phenomenon combines science and cultural tradition.
