Last Quarter in Gemini

Last Quarter on . Illuminated surface of the Moon is 44% and getting smaller. Lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 10 September 2085 at 21:07 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 leaving the last ∠3° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

Hunter Moon after 21 days

Next Full Moon is the Hunter Moon of October 2085 after 21 days on 3 October 2085 at 08:53.

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 ∠1824"

Lunar disc appears visually 4.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1824" and ∠1907".

Lunation 1059 / 2012

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 1059 of Meeus index or 2012 from Brown series.

Synodic month length 29.66 days

The length of this lunation is 29 days, 15 hours and 56 minutes and it is 3 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2085. 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 longer than mean

The length of the current synodic month is 3 hours and 12 minutes longer than the mean synodic month length. It is 3 hours and 51 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠180.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠180.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠204.1°.

Moon before apogee

7 days since point of perigee on 3 September 2085 at 13:43 in ♒ Aquarius 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 16 September 2085 at 12:30 in ♌ Leo.

Distance to Moon 392 977 km

The Moon is 392 977 km (244 185 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 406 253 km (252 434 mi).

Moon in descending node

Moon is in descending node in ♊ Gemini at 15:17 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 14 days until Moon's next ascending node later on 26 September 2085 at 04:15 in ♐ Sagittarius.

Moon after northern standstill

1 day since the last northern standstill on 10 September 2085 at 21:10 in ♊ Gemini when the Moon has reached North declination of ∠23.764° the lunar orbit is extending southward over the next 14 days to face maximum declination of ∠-23.613° at the point of next southern standstill on 25 September 2085 at 14:25 in ♐ Sagittarius.

Draconic month

12 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the middle to the last part of the lunar cycle.

Syzygy in 7 days

In 7 days on 19 September 2085 at 01:07 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.
