Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 3°54' to the south of Saturn. The Moon will be 15 days old.

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

From Columbus , the pair will be visible between 21:46 and 05:56. They will become accessible at around 21:46, when they rise to an altitude of 10° above your south-eastern horizon. They will reach their highest point in the sky at 01:51, 34° above your southern horizon. They will become inaccessible at around 05:56 when they sink below 10° above your south-western horizon.

The Moon will be at mag -12.7, and Saturn at mag 0.3, both in the constellation Capricornus.

The pair will be too widely separated to fit 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 21h38m20s 19°23'S Capricornus -12.7 33'01"4
Saturn 21h38m20s 15°28'S Capricornus 0.3 18"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 174° from the Sun, which is in Leo at this time of year.
