Moon phase and lunation details

4 days after New Moon

Previous main lunar phase is the New Moon before 4 days on 10 December 2091 at 13:54.

Moonrise and moonset

Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Moon in ♒ Aquarius

Moon is leaving the last ∠2° of ♒ Aquarius tropical zodiac sector and will enter ♓ Pisces later.

Apparent angular diameter ∠1848"

Lunar disc appears visually 5.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1848" and ∠1950".

Cold Moon after 10 days

Next Full Moon is the Cold Moon of December 2091 after 10 days on 25 December 2091 at 21:59.

Upcoming main Moon phases

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 5 days young. Earth's natural satellite is moving from the beginning to 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

6 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 5 days, until the Moon reaches the point of next apogee on 21 December 2091 at 10:59 in ♉ Taurus.

Previous perigeeNext apogee

Distance to Moon 387 894 km

The Moon is 387 894 km (241 026 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 405 544 km (251 993 mi).

Moon in descending node

Moon is in descending node in ♒ Aquarius at 07:03 crossing the ecliptic from North to South to meet ascending node 14 days later on 29 December 2091 at 20:00 in ♌ Leo.

Draconic month

12 days since the beginning of current draconic month in ♌ Leo, the Moon is navigating from the middle to the last part of the cycle.

Moon after southern standstill

3 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 10 days to face maximum declination of ∠19.486° at the point of next northern standstill on 26 December 2091 at 05:43 in ♋ Cancer.

Previous standstillNext standstill

Syzygy in 10 days

In 10 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.
