Moonrise and moonset

Moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.

Moon is entering ♋ Cancer

Moon is passing first ∠2° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1973"

Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1951".

Synodic month length 29.82 days

The length of the lunation is 29 days, 19 hours and 47 minutes. This is the year's longest synodic month of 2018. It is 59 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 7 hours and 3 minutes longer than the mean synodic month length and it is the longest synodic month length of 21st century.

Lunar orbit position on

True anomaly ∠173.3°

At the beginning of the lunation cycle the true anomaly is ∠173.3°. At the beginning of next synodic month the true anomaly is going to be ∠198.1°.

Moon at perigee

Moon is at perigee at 21:54. It is 13 days after previous apogee on 19 December 2017 at 01:27 in ♑ Capricorn. Lunar orbit is going to widen while the Moon is moving away from the Earth over the next 13 days, until point of next apogee on 15 January 2018 at 02:10 in ♑ Capricorn.

Distance to Moon 356 566 km

This perigee Moon is 356 566 km (221 560 mi) away from Earth. This is the year's closest perigee of 2018. It is 5 942 km closer than the mean perigee distance, but it is still 141 km further than the closest perigee of 21st century.

Moon before ascending node

10 days after descending node on 22 December 2017 at 10:04 in ♒ Aquarius. The Moon is located south of the ecliptic over the following 2 days, until the lunar orbit crosses from South to North in ascending node on 4 January 2018 at 07:48 in ♌ Leo.

Draconic month

24 days since the beginning of current draconic month in ♌ Leo, the Moon is navigating from the second to the final part of the cycle.

Moon before northern standstill

13 days since the previous standstill on 19 December 2017 at 09:31 in ♑ Capricorn when the Moon has reached South declination of ∠-20.062°, the lunar orbit is extending northward over the next day to face maximum declination of ∠20.055° at the point of next northern standstill on 2 January 2018 at 00:01 in ♋ Cancer.

Previous standstillNext standstill

Sun-Earth-Moon syzygy

The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
