Synodic month length 29.76 days

Length of current 25 lunation is 29 days, 18 hours and 12 minutes. It is 10 minutes shorter than next lunation 26 length.

Lunation length longer than mean

Length of current synodic month is 5 hours and 28 minutes longer than the mean length of synodic month, but it is still 1 hour and 35 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠123.9°

This New Moon true anomaly is ∠123.9°. At beginning of next synodic month true anomaly will be ∠155.3°. 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

3 days after point of apogee on 18 January 2002 at 08:50 in ♓ Pisces. 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 30 January 2002 at 09:02 in ♍ Virgo.

Distance to Moon 399 744 km

Moon is 399 744 km (248 389 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 359 997 km (223 692 mi).

Moon before northern standstill

8 days after previous South standstill on 12 January 2002 at 15:26 in ♑ Capricorn, when Moon has reached southern declination of ∠-24.240°. Next 5 days the lunar orbit moves northward to face North declination of ∠24.270° in the next northern standstill on 27 January 2002 at 01:56 in ♋ Cancer.
