Synodic month length 29.45 days

Length of current 172 lunation is 29 days, 10 hours and 52 minutes. This is the year's shortest synodic month of 2013. It is 28 minutes longer than next lunation 173 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 52 minutes shorter than the mean length of synodic month, but it is still 4 hours and 17 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠336.4°

This lunation true anomaly is ∠336.4°. At the beginning of next synodic month true anomaly will be ∠353°. 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

13 days after point of perigee on 4 December 2013 at 10:15 in ♑ Capricorn. 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 19 December 2013 at 23:49 in ♋ Cancer.

Distance to Moon 403 451 km

Moon is 403 451 km (250 693 mi) away from Earth on this date. Moon moves farther next 2 days until apogee, when Earth-Moon distance will reach 406 269 km (252 444 mi).

Moon after descending node

4 days after its descending node on 13 December 2013 at 10:10 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 10 days, until it will cross the ecliptic from South to North in ascending node on 28 December 2013 at 00:21 in ♏ Scorpio.

Moon in northern standstill

At 01:00 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠19.570°. Next 13 days the lunar orbit will move in opposite southward direction to face South declination of ∠-19.537° in its southern standstill point on 31 December 2013 at 04:49 in ♐ Sagittarius.
