Last Quarter in Gemini

Last Quarter on . Illuminated surface of the Moon is 55% and getting smaller. Lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 16 September 2090 at 23:48 UTC.

Moonrise and moonset

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

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♊ Gemini

Moon is passing about ∠18° of ♊ Gemini tropical zodiac sector.

Hunter Moon after 22 days

Next Full Moon is the Hunter Moon of October 2090 after 22 days on 8 October 2090 at 15:54.

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 ∠1860"

Lunar disc appears visually 2.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1860" and ∠1909".

Lunation 1121 / 2074

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 1121 of Meeus index or 2074 from Brown series.

Synodic month length 29.34 days

The length of this lunation is 29 days, 8 hours and 4 minutes and it is 1 hour and 2 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 4 hours and 40 minutes shorter than the mean synodic month length. It is 1 hour and 29 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠348.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠348.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠3.8°.

Moon after apogee

6 days since point of apogee on 9 September 2090 at 14:56 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 23 September 2090 at 11:39 in ♍ Virgo.

Distance to Moon 385 381 km

The Moon is 385 381 km (239 465 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 357 224 km (221 969 mi).

Moon before ascending node

7 days after descending node on 9 September 2090 at 07:13 in ♓ Pisces 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 23 September 2090 at 00:57 in ♍ Virgo.

Moon before northern standstill

13 days since the last southern standstill on 2 September 2090 at 19:58 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.232° the lunar orbit is extending northward over the next day to face maximum declination of ∠18.226° at the point of next northern standstill on 17 September 2090 at 14:20 in ♊ Gemini.

Draconic month

20 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 23 September 2090 at 17:03 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.
