Conjunction of the Moon and Mercury

The Moon and Mercury will share the same right ascension, with the Moon passing 3°35' to the north of Mercury. The Moon will be 2 days old.

From Fairfield , the pair will be difficult to observe as they will appear no higher than 10° above the horizon. They will become visible at around 17:06 (EST), 10° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 1 hour and 30 minutes after the Sun at 18:12.

The Moon will be at mag -8.9, and Mercury at mag -0.6, both in the constellation Capricornus.

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 Mercury 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 20h48m20s 14°47'S Capricornus -8.9 30'12"6
Mercury 20h48m20s 18°23'S Capricornus -0.6 7"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 20° from the Sun, which is in Sagittarius at this time of year.

Warning

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.
