The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 16 of Meeus index or 969 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.47 days

Length of current 16 lunation is 29 days, 11 hours and 20 minutes. It is 2 hours and 8 minutes longer than next lunation 17 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 24 minutes shorter than the mean length of synodic month, but it is still 4 hours and 45 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠267.3°

This lunation true anomaly is ∠267.3°. At the beginning of next synodic month true anomaly will be ∠299.7°. 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 in apogee

Moon is reaching point of apogee on this date at 01:29, this is 12 days after last perigee on 2 May 2001 at 03:37 in ♍ Virgo. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 11 days ahead, until it will get to the point of next perigee on 27 May 2001 at 07:07 in ♌ Leo.

Distance to Moon 404 141 km

This apogee Moon is 404 141 km (251 122 mi) away from Earth. This is the year's closest apogee of 2001. It is 1 267 km farther than the mean apogee distance, but it is still 90 km closer than the farthest apogee of 21st century.

Moon after descending node

4 days after its descending node on 11 May 2001 at 11:02 in ♑ Capricorn, 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 25 May 2001 at 13:51 in ♊ Gemini.

Moon after southern standstill

3 days after previous South standstill on 11 May 2001 at 20:26 in ♑ Capricorn, when Moon has reached southern declination of ∠-23.329°. Next 10 days the lunar orbit moves northward to face North declination of ∠23.388° in the next northern standstill on 25 May 2001 at 23:03 in ♋ Cancer.

Syzygy in 7 days

After 7 days on 23 May 2001 at 02:46 in ♊ Gemini, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
