Conjunction of the Moon and Mercury

From the Conjunctions feed


The Moon and Mercury will share the same right ascension, with the Moon passing 5°41' to the south of Mercury. The Moon will be 1 days old.

From Columbus however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 0° above the horizon at dusk.

The Moon will be at mag -8.3, and Mercury at mag 2.5, both in the constellation Taurus.

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 04h45m20s 17°42'N Taurus -8.3 31'43"3
Mercury 04h45m20s 23°24'N Taurus 2.5 10"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 15° from the Sun, which is in Taurus at this time of year.
