What is the moon phase tonight in Paris?

Tonight's moon phase for Paris is displayed in real time on MoonSync. The page loads with Paris's coordinates (48.9°, 2.4°) and shows the current moon illumination percentage, lunar age (days since new moon), moonrise and moonset times, and the moon's position above Paris's horizon. All calculations run client-side — no location data is sent anywhere.

When is the next full moon visible from Paris?

MoonSync's lunar calendar shows the full moon phase progression for any date and location, including Paris. Full moons occur approximately every 29.53 days. At 48.9° latitude, full moons near the winter solstice rise at their highest point in Paris's sky, while full moons near the summer solstice stay lower on the horizon — this seasonal variation is why winter full moons appear more dramatic from Paris.

How does the moon's phase affect stargazing in Paris?

Moon phase is the single most important factor for stargazing quality at Paris. A full moon (100% illumination) brightens the sky enough to obscure all but the brightest stars and makes deep-sky observation nearly impossible. For the best stargazing in Paris, plan sessions during the 7 days around New Moon when illumination is below 15%. Use MoonSync to find the next New Moon date, then use the Twilight Calculator to check when astronomical darkness begins.

Why does moonrise time change each day in Paris?

The moon rises approximately 50 minutes later each day as seen from Paris because the moon orbits Earth at about 1 km/s, moving approximately 13° eastward per day against the background stars. Since Earth rotates 360° in 24 hours (15°/hour), the extra 13° of rotation takes roughly 50 minutes. This daily delay explains why the moon is sometimes visible in Paris's daytime sky and why moonrise can occur at any hour of the day or night.

How Moon Phases Work at Paris's Latitude

Moon Phases Visible from Paris

From Paris at latitude 48.9°, the moon's appearance follows the same 29.53-day synodic cycle visible worldwide — all 8 phases from New Moon through Full Moon and back. However, Paris's high-latitude latitude affects the moon's maximum altitude in the sky. The moon can reach up to 69.7° altitude when crossing the meridian near summer solstice, and only 12.5° near winter solstice. This seasonal variation determines how high the moon appears above Paris's horizon and affects lunar photography planning.

Moonrise & Moonset Times at Paris

The moon rises approximately 50 minutes later each day as seen from Paris. This daily delay occurs because the moon orbits Earth eastward at about 1 km/s, moving roughly 13° per day against the background stars. At Paris's latitude (48.9°), the moon's rise and set positions along the horizon shift seasonally — rising further north in summer and further south in winter. MoonSync calculates exact moonrise and moonset times for Paris using real-time ephemeris data.

Moon Illumination & Paris's Dark-Sky Planning

For stargazing and astrophotography in Paris, moon illumination percentage is the critical number. A Full Moon (100% illuminated) washes out all but the brightest stars and makes deep-sky observation nearly impossible. The 7 days around New Moon (0-15% illumination) provide the best dark-sky window. At 48.9° latitude, combine moon phase with the Twilight Calculator to find nights when both astronomical darkness and minimal moonlight coincide — these 'astrophotographer's golden hours' occur roughly once per month at Paris.

Lunar Data Accuracy for Paris

MoonSync computes moon phase, illumination, moonrise/moonset times, and lunar age for Paris using real-time ephemeris data. Phase illumination is accurate to ±1%. Moonrise and moonset times are calculated from Paris's precise coordinates (48.9°, 2.4°) and corrected for atmospheric refraction. The Keplerian orbital model used achieves timing accuracy of approximately ±30 minutes over a synodic month. For sub-minute lunar event timing, consult the USNO Phases of the Moon data service.

How MoonSync Works

What Is Lunar Coordinated Time (LTC)?

LTC is a proposed Moon-based time standard. NASA's 2023 analysis found that Moon clocks gain +56.02 µs per Earth day: weaker lunar gravity causes a gravitational blueshift that outweighs the transverse Doppler redshift from lower orbital velocity. MoonSync accumulates this offset from J2000.0 (Jan 1, 2000 12:00 UTC).

NASA — What Time Is It on the Moon?

How Is Moon Illumination Percentage Calculated?

Moon illumination from Earth is the fraction of the Moon's visible disk lit by the Sun. At New Moon (0%), the Moon is between Earth and Sun, showing only its dark side. At Full Moon (100%), Earth is between Moon and Sun. The percentage follows a smooth sinusoidal curve over the 29.53-day synodic month. MoonSync calculates this in real-time using solar and lunar ephemeris data.

USNO — Moon Illumination Data

What Is a Permanent Shadow Region (PSR)?

PSRs are craters near the lunar poles never exposed to direct sunlight, due to the Moon's low axial tilt (1.54°). Temperatures hover around −230 °C, cold enough to trap water ice for billions of years. NASA's LCROSS mission (2009) confirmed water ice deposits in Cabeus crater near the south pole, making PSRs prime candidates for future lunar bases.

NASA Science — Permanently Shadowed Craters

How Is Earth–Moon Distance Calculated?

MoonSync uses a first-order Keplerian ellipse: r = a(1 − e·cos M), where a = 384,399 km (semi-major axis), e = 0.0549 (eccentricity), and M is the mean anomaly from perigee. Accuracy is ±3,000 km. For navigation-grade ephemerides, NASA/JPL's Horizons system integrates the full DE440 planetary solution.

الأسئلة الشائعة

What is Lunar Coordinated Time (LTC)?: LTC is a proposed Moon-based time standard. Because lunar gravity is weaker (gravitational blueshift) and the Moon's orbital speed is lower (transverse Doppler redshift), Moon clocks run approximately +56.02 µs faster per Earth day than Earth clocks. MoonSync cumulates this offset from J2000.0 (Jan 1, 2000, 12:00 UTC) to display the total LTC lead over UTC at any moment.
Why is the lunar surface temperature so extreme?: The Moon has no atmosphere to distribute or retain heat. In direct sunlight, temperatures reach +127 °C (400 K) at the sub-solar point; on the nightside they fall to −173 °C (100 K) — a 300 °C swing driven purely by the presence or absence of solar radiation. MoonSync estimates temperature using the Stefan–Boltzmann model: T (K) = 400 · sin(altitude)^0.25.
What is a Permanent Shadow Region (PSR)?: PSRs are polar craters on the Moon that have never received direct sunlight, due to the Moon's low axial tilt (1.54°). Temperatures can fall to −230 °C — cold enough to preserve water ice for billions of years. NASA's LCROSS mission (2009) confirmed water ice at the lunar south pole. MoonSync classifies any polar site (|lat| ≥ 87°) with negative solar altitude as a PSR.
How accurate are MoonSync's calculations?: MoonSync uses simplified Keplerian orbital elements and geometric optics suitable for education and illustration — not for navigation. Earth–Moon distance accuracy is ±3,000 km; LTC offset uses NASA's 2023 value of +56.0205 µs/day; phase timing drifts ≈±30 min over a synodic month. For navigation-grade results, consult JPL Horizons or USNO data.
When will the moon rise and set at my location?: MoonSync calculates moonrise and moonset times using your browser's location (or manually entered coordinates). The Moon rises roughly 50 minutes later each day due to its eastward orbital motion. Moonrise/moonset times depend on your latitude, the Moon's declination, and the current lunar phase. MoonSync uses real-time ephemeris data to compute accurate rise/set times and shows whether the Moon is currently above or below your horizon.
