The Moon and Saturn will share the same right ascension, with the Moon passing 2°58' to the south of Saturn. The Moon will be 21 days old.

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

From Ashburn, the pair will be visible in the dawn sky, rising at 01:08 (EDT) and reaching an altitude of 37° above the south-eastern horizon before fading from view as dawn breaks around 05:25.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

The Moon will be at mag -12.2, and Saturn at mag 0.7, both in the constellation Aquarius.

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 22h36m30s -13°25' Aquarius -12.2 32'21"3
Saturn 22h36m30s -10°26' Aquarius 0.7 17"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 102° from the Sun, which is in Taurus at this time of year.
