This Wednesday, November 5, 2025, the Moon reaches its full phase, making it the biggest supermoon of the year. The phenomenon, visible on all continents, occurs when the satellite is at perigee, the closest point to Earth, around 356 thousand kilometers. With 7.9% more size and 16% more brightness than a common full Moon, the event promises to attract the eyes of astronomers and curious people. The supermoon coincides with the proximity of the Pleiades star cluster, creating a unique spectacle in the night sky.
The full moon occurs at 10:19 am (Brasília time), with perigee at 7:27 pm, just nine hours later, according to the InTheSky.org platform. The phenomenon will be especially striking at dusk, when atmospheric refraction gives the Moon an orange hue. Viewers in cities such as São Paulo, New York and London will have privileged views, depending on weather conditions.
- Observation times: Rises at 5:36 pm, peaks at 11:15 pm and sets at 4:52 am.
- Best locations: Areas with little light pollution, such as rural areas.
- Viewing Tip: Use binoculars for details of the Pleiades.
The event does not require special equipment, making it accessible to everyone.
What defines a supermoon
A supermoon occurs when the full Moon coincides with perigee, the shortest distance from Earth in the lunar elliptical orbit. This proximity magnifies the apparent size and brightness of the satellite.
The lu orbitnar varies between 356 thousand and 406 thousand kilometers, a difference that creates the characteristic visual effect. According to experts, the phenomenon does not have great scientific relevance, but it is an opportunity to popularize astronomy.
Proximity to the Pleiades
November’s supermoon stands out for its position close to the Pleiades star cluster, known as “The Seven Sisters”. This group of stars, visible to the naked eye, is in the constellation Taurus.
The alignment creates a striking visual contrast, especially at dusk. Astronomers recommend observing the phenomenon in places with clear skies.
Binoculars or small telescopes can highlight the details of the Pleiades, enriching the experience.
Visual and cultural impact
In different cultures, the full moon inspires myths and celebrations. The supermoon intensifies this fascination, being portrayed in iconic photos, such as those captured in Paris and Rio de Janeiro.
The phenomenon attracts amateur and professional photographers, who look for urban or natural settings to record the event.
Atmospheric refraction at dusk increases the visual impact, with the Moon taking on golden or white tones.arranged.
In 2025, this is the second supermoon, after the one in August, and the last of the year.
Astronomy and science behind the event
The Moon’s elliptical orbit is the determining factor for the occurrence of supermoons. The average distance at perigee is 50,000 kilometers shorter than at apogee, according to Starwalk Space.
The term “supermoon” is not unanimous among astronomers, who see it as a scientific dissemination tool. Marcelo Zurita, from the Paraibana Astronomy Association, highlights that the phenomenon is more visual than scientifically relevant.
Despite this, the supermoon stimulates public interest in astronomy, encouraging group observations.
Similar events will occur in 2026, but with less proximity to perigee.
Observation Tips
To enjoy the supermoon, choose places with low light pollution. Coastal cities or rural areas are ideal.
Avoid powerful telescopes, as the proximity to the Moon can obscure details. Binoculars are enough to observe the Pleiades.
Check the weather forecast, as clouds can impede visibility.
