Synodic month length 29.57 days

Length of current 684 lunation is 29 days, 13 hours and 40 minutes. It is 2 hours and 22 minutes longer than next lunation 685 length.

Lunation length longer than mean

Length of current synodic month is 56 minutes longer than the mean length of synodic month, but it is still 6 hours and 7 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠221.6°

This lunation true anomaly is ∠221.6°. At the beginning of next synodic month true anomaly will be ∠254.3°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon before apogee

9 days after point of perigee on 8 May 2055 at 21:10 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 2 days, until it get to the point of next apogee on 20 May 2055 at 18:43 in ♓ Pisces.

Distance to Moon 402 575 km

Moon is 402 575 km (250 149 mi) away from Earth on this date. Moon moves farther next 2 days until apogee, when Earth-Moon distance will reach 404 756 km (251 504 mi).

Moon after descending node

1 day after its descending node on 17 May 2055 at 07:26 in ♒ Aquarius, 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 31 May 2055 at 13:01 in ♌ Leo.

Moon after southern standstill

3 days after previous South standstill on 14 May 2055 at 15:50 in ♑ Capricorn, when Moon has reached southern declination of ∠-20.280°. Next 10 days the lunar orbit moves northward to face North declination of ∠20.367° in the next northern standstill on 29 May 2055 at 04:41 in ♋ Cancer.
