Last Quarter in Gemini

Last Quarter on . The illuminated surface of the moon is 56% and getting smaller. The lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 6 September 2091 at 03:47 UTC.

Moonrise and moonset

The moon rises at midnight and sets at noon. It is visible to the south in the morning.

Moon phase and lunation details

Moon in ♊ Gemini

Moon is passing about ∠6° of ♊ Gemini tropical zodiac sector.

Harvest Moon after 22 days

Next Full Moon is the Harvest Moon of September 2091 after 22 days on 27 September 2091 at 15:56.

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.

Apparent angular diameter ∠1783"

Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1783" and ∠1904".

Lunation 1133 / 2086

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 1133 of Meeus index or 2086 from Brown series.

Synodic month length 29.38 days

The length of this lunation is 29 days, 9 hours and 13 minutes and it is 19 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 shorter than mean

The length of the current synodic month is 3 hours and 31 minutes shorter than the mean synodic month length. It is 2 hours and 38 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠310.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠310.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠332.3°.

Moon after apogee

2 days since point of apogee on 3 September 2091 at 01:49 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next perigee on 15 September 2091 at 01:40 in ♎ Libra.

Distance to Moon 401 918 km

The Moon is 401 918 km (249 740 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 361 131 km (224 396 mi).

Moon before ascending node

7 days after descending node on 28 August 2091 at 18:22 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from South to North in ascending node on 12 September 2091 at 03:32 in ♍ Virgo.

Moon before northern standstill

12 days since the last southern standstill on 24 August 2091 at 11:30 in ♑ Capricorn when the Moon has reached South declination of ∠-18.873° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠18.885° at the point of next northern standstill on 8 September 2091 at 00:27 in ♋ Cancer.

Draconic month

20 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.

Syzygy in 7 days

In 7 days on 13 September 2091 at 09:34 in ♍ Virgo the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
