Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 7'57" to the north of Saturn. The Moon will be 9 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 be visible in the evening sky, becoming accessible around 20:30 (EDT), 51° above your southern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 21:07, 52° above your southern horizon. They will continue to be observable until around 02:21, when they sink below 11° above your western horizon.

The Moon will be at mag -12.4, and Saturn at mag 0.8, both in the constellation Virgo.

The pair will be close enough to fit within the field of view of a telescope, but will also 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 11h40m10s 4°53'N Virgo -12.4 31'51"8
Saturn 11h40m10s 4°45'N Virgo 0.8 18"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 124° from the Sun, which is in Aries at this time of year.
