Moon phase and lunation details

Moonrise and moonset

Moon rises at sunrise and sets at sunset. It's part facing the Earth is completely in shadow.

Moon in ♐ Sagittarius

Moon is passing about ∠15° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter

Lunar disc is not visible from Earth. Moon and Sun apparent angular diameters are ∠1973" and ∠1947".

Cold Moon after 14 days

Next Full Moon is the Cold Moon of December 2021 after 14 days on 19 December 2021 at 04:36.

Upcoming main Moon phases

Spring tide

There is high New Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Moon-Earth syzygy alignment.

At 07:43 on this date the Moon completes the old and enters a new synodic month with lunation 271 of Meeus index or 1224 from Brown series.

Synodic month length 29.45 days

The length of the lunation is 29 days, 10 hours and 50 minutes. It is 23 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the 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 1 hour and 54 minutes shorter than the mean synodic month length. It is 4 hours and 15 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠358.3°

The true anomaly is ∠358.3°. At the beginning of the next synodic month the true anomaly is going to be ∠13.9°.

Moon at perigee

Moon is at perigee at 10:01. It is 13 days after previous apogee on 21 November 2021 at 02:14 in ♊ Gemini. Lunar orbit is going to widen while the Moon is moving away from the Earth over the next 13 days, until point of next apogee on 18 December 2021 at 02:16 in ♊ Gemini.

Previous apogeeNext apogee

Distance to Moon 356 794 km

This perigee Moon is 356 794 km (221 702 mi) away from Earth. This is the year's closest perigee of 2021. It is 5 714 km closer than the mean perigee distance, but it is still 369 km further than the closest perigee of 21st century.

Moon after descending node

1 day after descending node on 3 December 2021 at 14:58 in ♏ Scorpio. The Moon is located south of the ecliptic over the following 12 days, until the lunar orbit crosses from South to North in ascending node on 17 December 2021 at 00:12 in ♊ Gemini.

Draconic month

14 days since the beginning of current draconic month in ♉ Taurus, the Moon is navigating from the second to the final part of the cycle.

Moon before southern standstill

11 days since the previous standstill on 22 November 2021 at 22:43 in ♋ Cancer when the Moon has reached North declination of ∠26.342°, the lunar orbit is extending southward over the next day to face maximum declination of ∠-26.331° at the point of next southern standstill on 6 December 2021 at 02:25 in ♑ Capricorn.

Previous standstillNext standstill

Sun-Moon-Earth syzygy

The Moon is in a New Moon geocentric conjunction with the Sun and thus forming Sun-Moon-Earth syzygy alignment.
