The Moon and Saturn will share the same right ascension, with the Moon passing 4°06' to the south of Saturn. The Moon will be 6 days old.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From San Diego , the pair will become visible at around 17:20 (PST), 37° above your southern horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 22:18.

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 -11.7, and Saturn at mag 0.4, both in the constellation Capricornus.

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 20h39m50s 23°19'S Capricornus -11.7 31'54"5
Saturn 20h39m50s 19°13'S Capricornus 0.4 16"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 78° from the Sun, which is in Libra at this time of year.
