Moon phase and lunation details

5 days after Last Quarter

Previous main lunar phase is the Last Quarter before 5 days on 6 January 2021 at 09:37.

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 in ♐ Sagittarius

Moon is leaving the last ∠1° of ♐ Sagittarius tropical zodiac sector and will enter ♑ Capricorn later.

Apparent angular diameter ∠1936"

Lunar disc appears visually 0.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1936" and ∠1951".

Next Full Moon is the Wolf Moon of January 2021 after 17 days on 28 January 2021 at 19:16.

Upcoming main Moon phases

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.

Lunation 259 / 1212

The Moon is 27 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 259 of Meeus index or 1212 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.53 days

Length of current 259 lunation is 29 days, 12 hours and 44 minutes. It is 1 hour and 21 minutes shorter than next lunation 260 length.

Lunation length same as the mean

Length of current synodic month is equal to the mean length of synodic month. It is 6 hours and 9 minutes longer than the 21st century shortest and 7 hours and 3 minutes shorter than the 21st century longest synodic month.

Lunar orbit position on

True anomaly ∠30.1°

This New Moon true anomaly is ∠30.1°. At beginning of next synodic month true anomaly will be ∠53.8°. 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 perigee

1 day after point of perigee on 9 January 2021 at 15:39 in ♏ Scorpio. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 10 days, until it get to the point of next apogee on 21 January 2021 at 13:11 in ♉ Taurus.

Previous perigeeNext apogee

Distance to Moon 370 266 km

Moon is 370 266 km (230 073 mi) away from Earth on this date. Moon moves farther next 10 days until apogee, when Earth-Moon distance will reach 404 361 km (251 258 mi).

Moon after descending node

1 day after its descending node on 10 January 2021 at 20:15 in ♐ Sagittarius, the Moon is following the southern part of its orbit for the next 13 days, until it will cross the ecliptic from South to North in ascending node on 24 January 2021 at 21:47 in ♊ Gemini.

Moon before southern standstill

12 days after previous North standstill on 30 December 2020 at 07:53 in ♋ Cancer, when Moon has reached northern declination of ∠24.868°. Next day the lunar orbit moves southward to face South declination of ∠-24.870° in the next southern standstill on 12 January 2021 at 08:18 in ♑ Capricorn.

Syzygy in 1 day

After 1 day on 13 January 2021 at 05:00 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
