Fase Lunare Oggi

Che tu sia un astronomo, un semplice appassionato di osservazione del cielo o un fotografo in cerca dello scatto notturno perfetto, puoi utilizzare i dati riportati di seguito per monitorare il ciclo lunare e seguire con precisione la posizione della Luna nel firmamento.

Fase Lunare

The moon phase tells you where the moon sits in its 29.5-day synodic cycle, from new moon through waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent.

Segno Zodiacale della Luna

The moon sign shows which zodiac sign the moon occupies right now. The moon moves through all 12 signs roughly every 27.3 days, spending about 2.5 days in each.

Percentuale di Illuminazione

Illumination measures how much of the moon’s visible surface reflects sunlight toward Earth. At new moon it is 0%. At full moon it reaches 100%.

Età della Luna

Moon age counts the days elapsed since the last new moon. The lunar cycle runs 29.5 days from new moon to new moon.

Costellazione di Transito

The constellation shows which background star pattern the moon currently passes in front of, based on its position in the sky. The moon moves through the constellations of the ecliptic over its monthly orbit.

Diametro Angolare della Luna

The moon angle (also called the angular diameter or subtended angle) tells you how large the moon appears from Earth. A higher angle means the moon is closer and looks bigger.

Distanza Lunare

Moon distance measures how far the moon is from Earth at this moment. This varies because the moon follows an elliptical orbit. At perigee (closest approach) it is about 356,500 km away.

Altezza e Distanza del Sole

The sun angle shows the sun’s current position in the sky relative to the horizon. It determines daylight hours and solar elevation at your location.

Earth’s distance from the sun changes throughout the year as Earth follows its own elliptical orbit.

Il Ciclo Lunare

The moon completes one orbit around Earth every 27.3 days. This is called the sidereal month. But because Earth also moves around the sun, the moon needs about 29.5 days to return to the same phase as seen from Earth. This is the synodic month, and it drives the lunar calendar.

The eight main moon phases are: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent.

New moon occurs when the moon sits between Earth and the sun. The side facing Earth receives no direct sunlight. Illumination: 0%.

Full moon occurs when Earth sits between the moon and the sun. The side facing Earth is fully lit. Illumination: 100%.

Quarter moons (first and last) occur when the moon forms a 90° angle with the Earth-sun line. Illumination: 50%.

Distanza Lunare e Orbita Ellittica

The moon does not orbit Earth in a perfect circle. Its path is an ellipse, which means its distance from Earth changes constantly.

At perigee, the closest point in its orbit the moon can appear up to 14% larger and 30% brighter than at its farthest point. When a full moon coincides with perigee, it is commonly called a supermoon.

At apogee, the farthest point the moon appears smaller. If a total solar eclipse occurs when the moon is near apogee, the moon cannot fully cover the sun, producing an annular (ring) solar eclipse.

The moon angle value on this page reflects this distance change directly: a larger moon angle means the moon is closer.

Perché Monitorare la Fase Lunare?

Tracking the current moon phase is valuable for a wide variety of activities:

Astrophotography & Stargazing: A highly illuminated moon washes out faint stars and meteor showers. Knowing the moon age today helps you plan for dark, moonless nights.
Fishing and Tides: The moon distance and phase directly impact ocean tides. Anglers rely on lunar calendars to predict the best fishing times based on solunar theory.
Gardening and Agriculture: Many farmers plant and harvest by the phases of the moon and the current moon sign, a practice known as lunar gardening.
