Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 5°09' to the north of Saturn. The Moon will be 18 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 morning sky, becoming accessible around 00:29, when they reach an altitude of 10° above your south-eastern horizon. They will then reach their highest point in the sky at 04:25, 32° above your southern horizon. They will be lost to dawn twilight around 04:40, 32° above your southern horizon.

The Moon will be at mag -12.3 in the constellation Aquarius, and Saturn at mag 0.4 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 21h23m40s 11°04'S Aquarius -12.3 29'28"8
Saturn 21h23m40s 16°14'S Capricornus 0.4 18"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 128° from the Sun, which is in Taurus at this time of year.
