Full Moon in Cancer

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 25 December 2091 at 21:59 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 ♋ Cancer

Moon is passing about ∠12° of ♋ Cancer tropical zodiac sector.

It is Cold Moon

The Full Moon these days is the Cold of December 2091.

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 ∠1811"

Lunar disc appears visually 7.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1811" and ∠1951".

Lunation 1137 / 2090

The Moon is 15 days old and navigating through the middle part of the current synodic month. This is lunation 1137 of Meeus index or 2090 from Brown series.

Synodic month length 29.49 days

The length of this lunation is 29 days, 11 hours and 43 minutes and it is 1 hour and 43 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 1 minute shorter than the mean synodic month length. It is 5 hours and 8 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠20.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠20.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠40.9°.

Moon after apogee

5 days since point of apogee on 21 December 2091 at 10:59 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next perigee on 6 January 2092 at 12:22 in ♐ Sagittarius.

Distance to Moon 395 734 km

The Moon is 395 734 km (245 898 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 364 495 km (226 487 mi).

Moon before ascending node

11 days after descending node on 15 December 2091 at 07:03 in ♒ Aquarius 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 29 December 2091 at 20:00 in ♌ Leo.

Moon at northern standstill

At 05:43 the Moon is meeting its standstill point to reach North declination of ∠19.486°. This is the year's northernmost lunar standstill of 2091. Over the upcoming 12 days the lunar orbit is going to tilt southward to face maximum declination of ∠-19.466° at the point of next southern standstill in ♑ Capricorn on 8 January 2092 at 08:40.

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.
