Full Moon in Gemini

Full Moon on . The illuminated surface of the moon is 100%. The lunar cycle is 14 days old.

* The exact date and time of this Full Moon phase is on 18 December 2078 at 23:34 UTC.

Moonrise and moonset

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

Moon phase and lunation details

Moon in ♊ Gemini

Moon is passing about ∠20° of ♊ Gemini tropical zodiac sector.

It is Cold Moon

The Full Moon these days is the Cold of December 2078.

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 ∠1964"

Lunar disc appears visually 0.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1964" and ∠1950".

Lunation 976 / 1929

The Moon is 14 days old and navigating through the middle part of the current synodic month. This is lunation 976 of Meeus index or 1929 from Brown series.

Synodic month length 29.78 days

The length of this lunation is 29 days, 18 hours and 42 minutes and it is 1 hour and 57 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 5 hours and 58 minutes longer than the mean synodic month length. It is 1 hour and 5 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠196.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠196.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠225.6°.

Moon after perigee

1 day since point of perigee on 17 December 2078 at 21:10 in ♊ Gemini the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 30 December 2078 at 02:17 in ♏ Scorpio.

Distance to Moon 364 951 km

The Moon is 364 951 km (226 770 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 405 665 km (252 069 mi).

Moon after ascending node

2 days after ascending node on 15 December 2078 at 19:09 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 28 December 2078 at 21:50 in ♏ Scorpio.

Moon before northern standstill

11 days since the last southern standstill on 6 December 2078 at 12:06 in ♑ Capricorn when the Moon has reached South declination of ∠-27.555° the lunar orbit is extending northward over the next day to face maximum declination of ∠27.536° at the point of next northern standstill on 19 December 2078 at 14:06 in ♊ Gemini.

Draconic month

2 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the beginning to the first 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.
