Synodic month length 29.79 days

The length of the lunation is 29 days, 19 hours and 2 minutes. It is 22 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 longer than mean

The length of the current synodic month is 6 hours and 18 minutes longer than the mean synodic month length. It is 45 minutes shorter compared to 21st century's longest synodic month length.

True anomaly ∠148.4°

At the beginning of the lunation cycle the true anomaly is ∠148.4°. At the beginning of next synodic month the true anomaly is going to be ∠174.6°.

Moon before perigee

8 days after point of perigee on 9 December 2079 at 06:48 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 6 days, until the Moon reaches the point of next apogee on 23 December 2079 at 21:45 in ♑ Capricorn.

Distance to Moon 388 958 km

The Moon is 388 958 km (241 687 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 703 km (252 714 mi).

Moon before southern standstill

7 days since the previous standstill on 9 December 2079 at 17:56 in ♊ Gemini when the Moon has reached North declination of ∠28.228°, the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-28.189° at the point of next southern standstill on 23 December 2079 at 10:12 in ♑ Capricorn.

Previous standstillNext standstill

Syzygy in 5 days

In 5 days on 23 December 2079 at 06:31 in ♑ Capricorn 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.
