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°14' to the north of Mercury. The Moon will be 28 days old.

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 4° above the horizon at dawn.

The Moon will be at mag -9.1 in the constellation Pisces, and Mercury at mag -0.1 in the neighbouring constellation of Aquarius.

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 23h07m10s 1°53'S Pisces -9.1 32'32"9
Mercury 23h07m10s 8°08'S Aquarius -0.1 5"9

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

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
