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 27 September 2051 at 01:22 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 leaving the last ∠4° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

Hunter Moon after 23 days

Next Full Moon is the Hunter Moon of October 2051 after 23 days on 19 October 2051 at 19:13.

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 ∠1925"

Lunar disc appears visually 0.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1925" and ∠1914".

Lunation 639 / 1592

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 639 of Meeus index or 1592 from Brown series.

Synodic month length 29.68 days

The length of this lunation is 29 days, 16 hours and 14 minutes and it is 1 hour and 58 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 longer than mean

The length of the current synodic month is 3 hours and 29 minutes longer than the mean synodic month length. It is 3 hours and 33 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠137°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠137° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠163.9°.

Moon after perigee

4 days since point of perigee on 21 September 2051 at 12:20 in ♈ Aries the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next apogee on 6 October 2051 at 15:34 in ♎ Libra.

Distance to Moon 372 371 km

The Moon is 372 371 km (231 381 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 406 415 km (252 535 mi).

Moon after descending node

4 days after descending node on 22 September 2051 at 03:59 in ♈ Aries the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 5 October 2051 at 20:55 in ♎ Libra.

Moon at northern standstill

At 07:36 the Moon is meeting its standstill point to reach North declination of ∠18.704°. Over the upcoming 14 days the lunar orbit is going to tilt southward to face maximum declination of ∠-18.669° at the point of next southern standstill in ♐ Sagittarius on 10 October 2051 at 22:36.

Draconic month

17 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 8 days

In 8 days on 4 October 2051 at 20:47 in ♎ Libra 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.
