Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 3°48' to the north of Saturn. The Moon will be 5 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 19:37 (EDT), 20° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 2 hours and 54 minutes after the Sun at 21:59.

The Moon will be at mag -11.0, and Saturn at mag 0.4, both in the constellation Ophiuchus.

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 16h41m50s 16°58'S Ophiuchus -11.0 29'32"1
Saturn 16h41m50s 20°47'S Ophiuchus 0.4 15"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 58° from the Sun, which is in Virgo at this time of year.
