Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 46' to the north of Saturn. The Moon will be 11 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 17:14 (EDT), 25° above your south-eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 20:55, 49° above your southern horizon. They will continue to be observable until around 01:58, when they sink below 10° above your western horizon.

The Moon will be at mag -12.4, and Saturn at mag 0.5, both in the constellation Cetus.

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

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 00h28m40s 1°01'N Cetus -12.4 29'32"3
Saturn 00h28m40s 0°14'N Cetus 0.5 19"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 136° from the Sun, which is in Libra at this time of year.
