Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 6°52' to the north of Saturn. The Moon will be 14 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 between 20:04 and 04:18. They will become accessible at around 20:04, when they rise to an altitude of 10° above your south-eastern horizon. They will reach their highest point in the sky at 00:11, 34° above your southern horizon. They will become inaccessible at around 04:18 when they sink below 10° above your south-western horizon.

The Moon will be at mag -12.5 in the constellation Aquarius, and Saturn at mag 0.3 in the neighbouring constellation of Capricornus.

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 21h55m50s 7°21'S Aquarius -12.5 29'42"6
Saturn 21h55m50s 14°13'S Capricornus 0.3 18"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 169° from the Sun, which is in Leo at this time of year.
