Waning Gibbous in Gemini

Waning Gibbous on . Illuminated surface of the Moon is 97% and getting smaller. Lunar cycle is 16 days old.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♊ Gemini

Moon is passing about ∠23° of ♊ Gemini tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 21 November 2010 at 17:27.

Beaver Moon before 1 day

Next Full Moon is the Cold Moon of December 2010 after 27 days on 21 December 2010 at 08:13.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1881"

Lunar disc appears visually 3.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1881" and ∠1943".

Lunation 134 / 1087

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 134 of Meeus index or 1087 from Brown series.

Synodic month length 29.53 days

The length of this lunation is 29 days, 12 hours and 44 minutes and it is 2 hours and 43 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 same as the mean

The length of the current synodic month is equal to the mean synodic month length. It is %hours_to_shortest% and %minutes_to_shortest% longer than the 21st century's shortest and %hours_to_longest% and %minutes_to_longest% shorter than the 21st century's longest synodic months.

Lunar orbit details for

True anomaly ∠39.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠39.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠67°.

Moon before perigee

8 days since point of apogee on 15 November 2010 at 11:47 in ♓ Pisces 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 30 November 2010 at 19:09 in ♍ Virgo.

Distance to Moon 381 156 km

The Moon is 381 156 km (236 839 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 369 439 km (229 559 mi).

Moon before descending node

13 days after ascending node on 9 November 2010 at 20:14 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 24 November 2010 at 06:27 in ♋ Cancer.

Moon at northern standstill

At 04:24 the Moon is meeting its standstill point to reach North declination of ∠24.238°. This is the year's northernmost lunar standstill of 2010. Over the upcoming 12 days the lunar orbit is going to tilt southward to face maximum declination of ∠-24.233° at the point of next southern standstill in ♐ Sagittarius on 6 December 2010 at 02:10.

Draconic month

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

Syzygy in 12 days

In 12 days on 5 December 2010 at 17:36 in ♐ Sagittarius 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.
