Conjunction of the Moon and Mercury

From the Conjunctions feed


The Moon and Mercury will share the same right ascension, with the Moon passing 1°18' to the north of Mercury. The Moon will be 2 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 2° above the horizon at dusk.

The Moon will be at mag -9.2, and Mercury at mag -0.2, both in the constellation Libra.

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 14h51m50s 17°27'S Libra -9.2 33'06"8
Mercury 14h51m50s 18°45'S Libra -0.2 5"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 21° from the Sun, which is in Virgo at this time of year.
