Full Moon in Gemini

Full Moon on . Illuminated surface of the Moon is 100%. Lunar cycle is 15 days old.

* The exact date and time of this Full Moon phase is on 4 December 2055 at 05:40 UTC.

Moonrise and moonset

Moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♊ Gemini

Moon is passing about ∠15° of ♊ Gemini tropical zodiac sector.

It is Cold Moon

The Full Moon these days is the Cold of December 2055.

Spring tide

There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.

Apparent angular diameter ∠1813"

Lunar disc appears visually 7.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1813" and ∠1947".

Lunation 691 / 1644

The Moon is 15 days old and navigating through the middle part of the current synodic month. This is lunation 691 of Meeus index or 1644 from Brown series.

Synodic month length 29.49 days

The length of this lunation is 29 days, 11 hours and 41 minutes and it is 2 hours and 14 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 1 hour and 3 minutes shorter than the mean synodic month length. It is 5 hours and 6 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠24.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠24.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠45.5°.

Moon after apogee

5 days since point of apogee on 29 November 2055 at 09:39 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next perigee on 15 December 2055 at 10:52 in ♏ Scorpio.

Distance to Moon 395 330 km

The Moon is 395 330 km (245 647 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 365 611 km (227 180 mi).

Moon before ascending node

10 days after descending node on 23 November 2055 at 14:19 in ♑ Capricorn the Moon is positioned south of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from South to North in ascending node on 8 December 2055 at 02:26 in ♌ Leo.

Moon before northern standstill

12 days since the last southern standstill on 21 November 2055 at 23:06 in ♑ Capricorn when the Moon has reached South declination of ∠-21.087° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠21.161° at the point of next northern standstill on 6 December 2055 at 12:59 in ♋ Cancer.

Draconic month

23 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the second to the final part of the lunar cycle.

Sun-Earth-Moon syzygy

The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
