Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 37' to the north of Saturn. The Moon will be 18 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 morning sky, becoming accessible around 19:18, when they reach an altitude of 9° above your eastern horizon. They will then reach their highest point in the sky at 01:44, 68° above your southern horizon. They will be lost to dawn twilight around 05:54, 33° above your western horizon.

The Moon will be at mag -12.6, and Saturn at mag -0.4, both in the constellation Taurus.

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 04h50m10s 21°12'N Taurus -12.6 31'07"0
Saturn 04h50m10s 20°34'N Taurus -0.4 20"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 147° from the Sun, which is in Libra at this time of year.
