The Moon and Saturn will make a close approach, passing within 4°53' of each other. The Moon will be 21 days old.

From Fairfield , the pair will be visible in the morning sky, becoming accessible around 23:41, when they reach an altitude of 9° above your eastern horizon. They will then reach their highest point in the sky at 06:07, 70° above your southern horizon. They will be lost to dawn twilight around 06:39, 69° above your southern horizon.

The Moon will be at mag -12.0; and Saturn will be at mag -0.2. Both objects will lie in the constellation Gemini.

They 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.

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 06h57m30s 26°57'N Gemini -12.0 29'54"5
Saturn 06h56m40s 22°03'N Gemini -0.2 18"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 100° from the Sun, which is in Virgo at this time of year.
