Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 6°47' to the north of Saturn. The Moon will be 13 days old.

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

From South El Monte , the pair will be visible between 17:09 and 05:21. They will become accessible at around 17:09, when they rise to an altitude of 9° above your eastern horizon. They will reach their highest point in the sky at 23:15, 74° above your southern horizon. They will become inaccessible at around 05:21 when they sink below 9° above your western horizon.

The Moon will be at mag -12.8, and Saturn at mag -0.4, both in the constellation Taurus.

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 04h05m10s 25°26'N Taurus -12.8 32'50"8
Saturn 04h05m10s 18°38'N Taurus -0.4 20"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 173° from the Sun, which is in Ophiuchus at this time of year.
