Moon phase and lunation details
Moonrise and moonset
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon in ♓ Pisces
Moon is passing about ∠23° of ♓ Pisces tropical zodiac sector.
Apparent angular diameter ∠1807"
Lunar disc appears visually 7.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1807" and ∠1950".
Cold Moon after 8 days
Next Full Moon is the Cold Moon of December 2091 after 8 days on 25 December 2091 at 21:59.
Upcoming main Moon phases
- Full Moon in Gemini ♊ on 25 December 2091 at 21:59
- Last Quarter in Libra ♎ on 2 January 2092 at 09:07
- New Moon in Capricorn ♑ on 9 January 2092 at 01:37

Neap tide
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
Lunation 1137 / 2090
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 1137 of Meeus index or 2090 from Brown series.
Synodic month length 29.49 days
The length of the lunation is 29 days, 11 hours and 43 minutes. It is 1 hour and 43 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the 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 position on
True anomaly ∠20.8°
At the beginning of the lunation cycle the true anomaly is ∠20.8°. At the beginning of next synodic month the true anomaly is going to be ∠40.9°.
Moon before perigee
8 days after point of perigee on 9 December 2091 at 08:19 in ♐ Sagittarius. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 3 days, until the Moon reaches the point of next apogee on 21 December 2091 at 10:59 in ♉ Taurus.
Distance to Moon 396 709 km
The Moon is 396 709 km (246 504 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 405 544 km (251 993 mi).
Moon after descending node
2 days after descending node on 15 December 2091 at 07:03 in ♒ Aquarius. The Moon is located south of the ecliptic over the following 12 days, until the lunar orbit crosses from South to North in ascending node on 29 December 2091 at 20:00 in ♌ Leo.
Draconic month
14 days since the beginning of current draconic month in ♌ Leo, the Moon is navigating from the second to the final part of the cycle.
Moon after southern standstill
5 days since the previous standstill on 11 December 2091 at 21:10 in ♑ Capricorn when the Moon has reached South declination of ∠-19.452°, the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠19.486° at the point of next northern standstill on 26 December 2091 at 05:43 in ♋ Cancer.
Syzygy in 8 days
In 8 days on 25 December 2091 at 21:59 in ♊ Gemini the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
