Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 13' to the south 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 17:02 (EDT), 40° above your south-eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 18:10, 42° above your southern horizon. They will continue to be observable until around 22:45, when they sink below 11° above your western horizon.

The Moon will be at mag -11.9, and Saturn at mag 0.8, both in the constellation Aquarius.

The pair will be close enough to fit within the field of view of a telescope, but will also 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 23h25m20s 6°23'S Aquarius -11.9 29'35"2
Saturn 23h25m20s 6°09'S Aquarius 0.8 17"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 94° from the Sun, which is in Ophiuchus at this time of year.
