Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 28' to the north 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 between 17:19 and 06:11. They will become accessible at around 17:19, when they rise to an altitude of 8° above your eastern horizon. They will reach their highest point in the sky at 23:45, 67° above your southern horizon. They will become inaccessible at around 06:11 when they sink below 8° above your western horizon.

The Moon will be at mag -12.7, and Saturn at mag -0.5, both in the constellation Taurus.

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 04h41m30s 20°48'N Taurus -12.7 31'21"4
Saturn 04h41m30s 20°19'N Taurus -0.5 20"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 176° from the Sun, which is in Ophiuchus at this time of year.
