Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 5°16' to the north of Saturn. The Moon will be 8 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 evening sky, becoming accessible around 17:21 (EDT), 29° above your southern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 18:02, 30° above your southern horizon. They will continue to be observable until around 21:50, when they sink below 10° above your south-western horizon.

The Moon will be at mag -11.9 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 20h59m40s 12°51'S Aquarius -11.9 29'36"2
Saturn 20h59m40s 18°08'S Capricornus 0.4 16"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 93° from the Sun, which is in Libra at this time of year.
