Conjunction of the Moon and Mercury

From the Conjunctions feed


The Moon and Mercury will share the same right ascension, with the Moon passing 6°33' to the north of Mercury. The Moon will be 28 days old.

From Fairfield however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 6° above the horizon at dawn.

The Moon will be at mag -9.0, and Mercury at mag -0.2, both in the constellation Taurus.

The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.

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 04h28m30s 25°52'N Taurus -9.0 32'59"4
Mercury 04h28m30s 19°19'N Taurus -0.2 6"8

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