The Moon and Saturn will make a close approach, passing within 1°47' of each other. The Moon will be 6 days old.

From Ashburn, the pair will become visible around 18:51 (EST) as the dusk sky fades, 26° above your southern horizon. They will then sink towards the horizon, setting at 22:36.

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 -11.4; and Saturn will be at mag 0.3. Both objects will lie in the constellation Sagittarius.

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 18h15m30s -20°59' Sagittarius -11.4 29'52"9
Saturn 18h15m00s -22°46' Sagittarius 0.3 16"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 72° from the Sun, which is in Virgo at this time of year.
