Last Quarter in Gemini

Last Quarter on . The illuminated surface of the moon is 54% and getting smaller. The lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 2 September 2037 at 22:03 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 ∠5° of ♊ Gemini tropical zodiac sector.

Harvest Moon after 21 days

Next Full Moon is the Harvest Moon of September 2037 after 21 days on 24 September 2037 at 11:32.

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 ∠1834"

Lunar disc appears visually 3.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1834" and ∠1902".

Lunation 465 / 1418

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 465 of Meeus index or 1418 from Brown series.

Synodic month length 29.32 days

The length of this lunation is 29 days, 7 hours and 44 minutes and it is 25 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2037. 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 5 hours shorter than the mean synodic month length. It is 1 hour and 9 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠338.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠338.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠354.5°.

Moon after apogee

5 days since point of apogee on 28 August 2037 at 00:28 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 10 September 2037 at 02:13 in ♍ Virgo.

Distance to Moon 390 802 km

The Moon is 390 802 km (242 833 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 357 229 km (221 972 mi).

Moon before ascending node

10 days after descending node on 22 August 2037 at 23:10 in ♑ Capricorn 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 6 September 2037 at 10:34 in ♋ Cancer.

Moon before northern standstill

11 days since the last southern standstill on 21 August 2037 at 14:16 in ♑ Capricorn when the Moon has reached South declination of ∠-21.390° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠21.473° at the point of next northern standstill on 5 September 2037 at 06:20 in ♋ Cancer.

Draconic month

23 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 9 September 2037 at 18:25 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.
