Lunar Concepts
Supermoon
Astrology meaning, traditional reading, and frequently asked questions.
Quick Definition
A full or new moon occurring near the Moon’s closest approach to Earth — visibly larger and astrologically amplified.
What Supermoon Means
A supermoon is a full moon or new moon that occurs when the Moon is at or near perigee — its closest point to Earth in its monthly orbit. Astronomically, the Moon appears about 14% larger and 30% brighter than at apogee. The term itself was coined by astrologer Richard Nolle in 1979. Astrologically, supermoons are read as amplified versions of the lunar themes already present — a full supermoon intensifies the full-moon culmination; a new supermoon intensifies the new-moon seeding. Several supermoons typically occur each year.
How to Spot Supermoon in Your Chart
To find when a Supermoon occurs, check an astrological calendar or ephemeris. The phase is identified by the relationship between the Sun and the Moon — calendars list the exact date, time, and zodiac sign of every Supermoon.
For natal work, look at your birth chart for the lunar phase you were born under — the relationship between your natal Sun and natal Moon describes a permanent feature of your temperament. For predictive work, compare current lunar events to your natal chart to see which houses and natal planets they activate.
Concrete Example
A full supermoon in Aries is traditionally read as a strongly emphasised moment of self-assertion, identity, and personal action — Aries themes amplified by the supermoon’s proximity.
What Supermoon Traditionally Indicates
Lunar astrology is among the oldest layers of the craft. The Babylonians tracked the Moon’s cycles for divinatory purposes; Hellenistic and Vedic astrologers built sophisticated systems around lunar mansions, nodes, and phases. Supermoon sits within this long tradition of lunar interpretation.
Modern lunar work, especially the popular intention-setting traditions around new and full moons, draws on these older techniques but reframes them for contemporary practice. The literal observation has stayed the same — the Moon still moves through its phases as it always has — but the meanings have been re-coloured by each generation of practitioners.
Frequently Asked Questions
Is a supermoon astrologically more powerful?
Astrologers generally treat supermoons as amplifications of ordinary lunar themes rather than as unique events. The proximity to Earth is read as a symbolic “closer” presence of lunar themes — a stronger version of an already-meaningful moment.
Who coined the term supermoon?
Astrologer Richard Nolle coined the term in 1979. It only entered mainstream astronomical and media use much later, around the 2010s.
How many supermoons are there per year?
Typically three to four full supermoons and a similar number of new supermoons per year. The exact count depends on the precise definition used.
Does a supermoon look bigger to the eye?
Slightly, but the difference is subtle in real-world viewing — about 14% larger than the smallest full moon. Atmospheric effects near the horizon often produce a more dramatic apparent enlargement than the supermoon effect itself.
