Conjunction of the Moon and Saturn

From the Conjunctions feed


The Moon and Saturn will share the same right ascension, with the Moon passing 18' to the north of Saturn. The Moon will be 25 days old.

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

From Cambridge however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 10° above the horizon at dawn.

The Moon will be at mag -10.7, and Saturn at mag 1.1, 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 23h36m50s 4°15'S Aquarius -10.7 30'02"1
Saturn 23h36m50s 4°34'S Aquarius 1.1 16"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 49° from the Sun, which is in Aries at this time of year.
