Synodic month length 29.79 days

Length of current 1101 lunation is 29 days, 18 hours and 58 minutes. This is the year's longest synodic month of 2089. It is 1 hour and 50 minutes longer than next lunation 1102 length.

Lunation length longer than mean

Length of current synodic month is 6 hours and 14 minutes longer than the mean length of synodic month, but it is still 49 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠185.7°

This lunation true anomaly is ∠185.7°. At the beginning of next synodic month true anomaly will be ∠211.9°. 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 after perigee

5 days after point of perigee on 25 January 2089 at 19:36 in ♋ Cancer. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 6 days, until it get to the point of next apogee on 7 February 2089 at 10:18 in ♑ Capricorn.

Distance to Moon 383 393 km

Moon is 383 393 km (238 229 mi) away from Earth on this date. Moon moves farther next 6 days until apogee, when Earth-Moon distance will reach 406 252 km (252 433 mi).

New draconic month

At 14:33 on this date the Moon is completing its previous draconic month and is entering the new one.


Moon before southern standstill

7 days after previous North standstill on 23 January 2089 at 16:28 in ♊ Gemini, when Moon has reached northern declination of ∠18.817°. Next 5 days the lunar orbit moves southward to face South declination of ∠-18.740° in the next southern standstill on 5 February 2089 at 19:19 in ♐ Sagittarius.
