Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 4°24' to the south of Saturn. The Moon will be 26 days old.

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

From Fairfield , the pair will be visible in the dawn sky, rising at 04:12 (EDT) – 3 hours and 6 minutes before the Sun – and reaching an altitude of 21° above the south-eastern horizon before fading from view as dawn breaks at around 06:42.

The Moon will be at mag -10.5, and Saturn at mag 0.4, both in the constellation Scorpius.

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 16h17m50s 23°56'S Scorpius -10.5 32'50"3
Saturn 16h17m50s 19°31'S Scorpius 0.4 15"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 40° from the Sun, which is in Sagittarius at this time of year.
