Moon is 15 days old. Earth's natural satellite is moving through the middle part of current synodic month. This is lunation 165 of Meeus index or 1118 from Brown series.

Previous | Current lunation | Next

Synodic month length 29.64 days

Length of current 165 lunation is 29 days, 15 hours and 28 minutes. It is 10 minutes longer than next lunation 166. This is the longest synodic month of 2013.

Lunation length longer than mean

Length of current synodic month is 2 hours and 44 minutes longer than the mean length of synodic month, but it is still 4 hours and 19 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠143.3°

This lunation true anomaly is ∠143.3°. At the beginning of next synodic month true anomaly is ∠168.8°. The length of upcoming synodic months increases since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon before perigee

11 days after point of apogee on 13 May 2013 at 13:31, lunar orbit gets closer while the Moon moves inward the Earth. It keeps this direction for next 1 day until it gets to the point of perigee on 26 May 2013 at 01:45.

Distance to Moon 364 403 km

Moon is 364 403 km (226 430 mi) away from Earth on this date. At previous apogee point before 11 days, distance is 405 827 km (252 169 mi). Moon moves closer next 1 day until perigee, when Earth-Moon distance reaches 358 375 km (222 684 mi).

Moon after ascending node

1 day after its ascending node on 24 May 2013 at 00:40, the Moon follows the northern part of its orbit for the next 11 days untill it crosses the ecliptic from North to South in descending node on 6 June 2013 at 00:59.

Draconic month

1 day after its beginning, the Moon is moving from the beginning to the first part of current draconic month.

Previous | Current draconic month | Next

Moon before southern standstill

12 days after previous North standstill on 12 May 2013 at 12:30, when Moon reaches northern declination of ∠20.170°, lunar orbit moves southward for the next 1 day to face South declination of ∠-20.182° in the next southern standstill on 26 May 2013 at 04:47.

Sun-Earth-Moon syzygy

The Moon is in Full Moon opposition with the Sun on this date and this alignment forms Sun-Earth-Moon syzygy.
