The Moon and Saturn will make a close approach, passing within 0°18' of each other. The Moon will be 25 days old.

From Cambridge, the pair will be difficult to observe as they will appear no higher than 17° above the horizon. They will be visible in the dawn sky, rising at 03:46 (EDT) – 2 hours and 34 minutes before the Sun – and reaching an altitude of 17° above the south-eastern horizon before fading from view as dawn breaks around 06:02.

The Moon will be at mag -10.8, and Saturn at mag 0.4, both in the constellation Sagittarius.

The pair will be close enough to fit within the field of view of a telescope, but will also be visible to the naked eye or through a pair of binoculars.

At around the same time, the two objects 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 two objects at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 19h15m40s -21°32' Sagittarius -10.8 29'37"0
Saturn 19h15m40s -21°51' Sagittarius 0.4 15"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 53° from the Sun, which is in Aquarius at this time of year.
