Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 6°16' to the south of Saturn. The Moon will be 16 days old.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Cambridge , the pair will be visible in the morning sky, becoming accessible around 20:50, when they reach an altitude of 10° above your eastern horizon. They will then reach their highest point in the sky at 01:23, 39° above your southern horizon. They will be lost to dawn twilight around 05:43, 12° above your south-western horizon.

The Moon will be at mag -12.8, and Saturn at mag 0.2, both in the constellation Virgo.

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 13h42m50s 13°57'S Virgo -12.8 33'19"8
Saturn 13h42m50s 7°41'S Virgo 0.2 19"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 168° from the Sun, which is in Pisces at this time of year.
