Conjunction of the Moon and Saturn

From the Conjunctions feed


The Moon and Saturn will share the same right ascension, with the Moon passing 37' to the north of Saturn. The Moon will be 27 days old.

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

From Los Angeles however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 10° above the horizon at dawn.

The Moon will be at mag -9.5, and Saturn at mag 0.5, both in the constellation Sagittarius.

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 19h04m10s 21°32'S Sagittarius -9.5 29'35"9
Saturn 19h04m10s 22°09'S Sagittarius 0.5 15"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 27° from the Sun, which is in Capricornus at this time of year.
