The Moon and Saturn will make a close approach, passing within 0°57' of each other. The Moon will be 3 days old.

From Fairfield, the pair will become visible around 17:28 (EDT) as the dusk sky fades, 26° above your south-western horizon. They will then sink towards the horizon, setting 2 hours and 54 minutes after the Sun at 20:03.

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 -10.2; and Saturn will be at mag 1.0. Both objects will lie in the constellation Aquarius.

They will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.

At around the same time, the pair will also share the same right ascension – called a conjunction.

A graph of the angular separation between the Moon and Saturn around the time of closest approach is available here.

The positions of the pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 23h13m40s -06°01' Aquarius -10.2 32'27"7
Saturn 23h15m30s -06°52' Aquarius 1.0 15"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 34° from the Sun, which is in Capricornus at this time of year.
