Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 47' to the south of Saturn. The Moon will be 4 days old.

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

From Columbus , the pair will become visible at around 21:43 (EDT), 18° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 2 hours and 24 minutes after the Sun at 23:24.

The Moon will be at mag -10.8, and Saturn at mag 0.9, both in the constellation Leo.

The pair will be a little too widely separated to fit comfortably 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 11h13m50s 6°17'N Leo -10.8 31'30"2
Saturn 11h13m50s 7°05'N Leo 0.9 16"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 50° from the Sun, which is in Gemini at this time of year.
