Moon phase and lunation details

3 days after Last Quarter

Previous main lunar phase is the Last Quarter before 3 days on 11 December 2025 at 20:52.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon is entering ♏ Scorpio

Moon is passing first ∠4° of ♏ Scorpio tropical zodiac sector.

Synodic month length 29.79 days

The length of the lunation is 29 days, 18 hours and 56 minutes. This is the year's longest synodic month of 2025. It is 47 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the 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 6 hours and 12 minutes longer than the mean synodic month length. It is 51 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠181.4°

At the beginning of the lunation cycle the true anomaly is ∠181.4°. At the beginning of next synodic month the true anomaly is going to be ∠207°.

Moon before perigee

11 days after point of perigee on 4 December 2025 at 11:06 in ♊ Gemini. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next day, until the Moon reaches the point of next apogee on 17 December 2025 at 06:09 in ♏ Scorpio.

Distance to Moon 403 379 km

The Moon is 403 379 km (250 648 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 406 324 km (252 478 mi).

Moon after descending node

4 days after descending node on 11 December 2025 at 07:35 in ♍ Virgo. The Moon is located south of the ecliptic over the following 10 days, until the lunar orbit crosses from South to North in ascending node on 25 December 2025 at 22:03 in ♓ Pisces.

Moon before southern standstill

9 days since the previous standstill on 5 December 2025 at 21:51 in ♊ Gemini when the Moon has reached North declination of ∠28.263°, the lunar orbit is extending southward over the next 4 days to face maximum declination of ∠-28.233° at the point of next southern standstill on 19 December 2025 at 23:18 in ♐ Sagittarius.

Syzygy in 4 days

In 4 days on 20 December 2025 at 01:43 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.
