Waxing Gibbous in Gemini

Waxing Gibbous on . The illuminated surface of the moon is 99% and growing larger. The lunar cycle is 14 days young.

Moonrise and moonset

The moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Moon phase and lunation details

Moon in ♊ Gemini

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

6 days after First Quarter

Previous main lunar phase is the First Quarter before 6 days on 13 December 2010 at 13:59.

Cold Moon after 1 day

Next Full Moon is the Cold Moon of December 2010 after 1 day 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 ∠1867"

Lunar disc appears visually 4.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1867" and ∠1950".

Lunation 135 / 1088

The Moon is 14 days young and navigating from the first to the middle part of the current synodic month. This is lunation 135 of Meeus index or 1088 from Brown series.

Synodic month length 29.64 days

The length of this lunation is 29 days, 15 hours and 27 minutes and it is 2 hours and 1 minute 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 2 hours and 43 minutes longer than the mean synodic month length. It is 4 hours and 20 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠67°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠67° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠103.5°.

Moon before perigee

7 days since point of apogee on 13 December 2010 at 08:34 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 25 December 2010 at 12:24 in ♌ Leo.

Distance to Moon 383 824 km

The Moon is 383 824 km (238 497 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 368 463 km (228 952 mi).

Moon before descending node

13 days after ascending node on 7 December 2010 at 04:15 in ♑ Capricorn 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 21 December 2010 at 14:08 in ♊ Gemini.

Moon at northern standstill

At 12:37 the Moon is meeting its standstill point to reach North declination of ∠24.238°. Over the upcoming 12 days the lunar orbit is going to tilt southward to face maximum declination of ∠-24.242° at the point of next southern standstill in ♐ Sagittarius on 2 January 2011 at 10:06.

Draconic month

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

Syzygy in 1 day

In 1 day on 21 December 2010 at 08:13 in ♊ Gemini the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
