Next Full Moon is the Cold Moon of December 2018 after 7 days on 22 December 2018 at 17:49.

Upcoming main Moon phases

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 234 of Meeus index or 1187 from Brown series.

Synodic month length 29.76 days

Length of current 234 lunation is 29 days, 18 hours and 8 minutes. It is 1 hour and 27 minutes shorter than next lunation 235 length.

Lunation length longer than mean

Length of current synodic month is 5 hours and 24 minutes longer than the mean length of synodic month, but it is still 1 hour and 39 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠116.6°

This New Moon true anomaly is ∠116.6°. At beginning of next synodic month true anomaly will be ∠149.4°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon after apogee

2 days after point of apogee on 12 December 2018 at 12:25 in ♒ Aquarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 24 December 2018 at 09:52 in ♋ Cancer.

Distance to Moon 400 309 km

Moon is 400 309 km (248 740 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 361 060 km (224 352 mi).

Moon after descending node

4 days after its descending node on 10 December 2018 at 17:57 in ♑ Capricorn, the Moon is following the southern part of its orbit for the next 8 days, until it will cross the ecliptic from South to North in ascending node on 24 December 2018 at 11:54 in ♋ Cancer.

Moon after southern standstill

6 days after previous South standstill on 9 December 2018 at 11:12 in ♑ Capricorn, when Moon has reached southern declination of ∠-21.539°. Next 7 days the lunar orbit moves northward to face North declination of ∠21.550° in the next northern standstill on 23 December 2018 at 11:48 in ♋ Cancer.

Syzygy in 7 days

After 7 days on 22 December 2018 at 17:49 in ♊ Gemini, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
