The Moon and Saturn will share the same right ascension, with the Moon passing 3°35' to the south of Saturn. The Moon will be 27 days old.

From Ashburn however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 7° above the horizon at dawn.

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 -9.8, and Saturn at mag 0.8, 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 22h14m10s -15°54' Aquarius -9.8 32'55"7
Saturn 22h14m10s -12°18' Aquarius 0.8 15"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 28° from the Sun, which is in Pisces at this time of year.
