Conjunction of the Moon and Saturn

From the Conjunctions feed


The Moon and Saturn will share the same right ascension, with the Moon passing 5°30' to the north of Saturn. The Moon will be 19 days old.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Fairfield , the pair will be visible in the dawn sky, rising at 23:13 (EDT) and reaching an altitude of 44° above the southern horizon before fading from view as dawn breaks at around 04:49.

The Moon will be at mag -12.3 in the constellation Pisces, and Saturn at mag 0.8 in the neighbouring constellation of Aquarius.

The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.

A graph of the angular separation between the Moon and Saturn around the time of closest approach is available here.

The positions of the two objects at the moment of conjunction will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 23h44m00s 1°24'N Pisces -12.3 31'13"6
Saturn 23h44m00s 4°05'S Aquarius 0.8 18"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 117° from the Sun, which is in Gemini at this time of year.
