Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 5°10' to the north of Saturn. The Moon will be 8 days old.

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

From Cambridge , the pair will become visible at around 17:38 (EST), 62° above your southern horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 00:25.

The Moon will be at mag -11.8, and Saturn at mag -0.0, both in the constellation Aries.

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

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 03h05m00s 20°21'N Aries -11.8 29'32"5
Saturn 03h05m00s 15°10'N Aries -0.0 18"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 88° from the Sun, which is in Capricornus at this time of year.
