The Moon and Mercury will share the same right ascension, with the Moon passing 2°23' to the south of Mercury. The Moon will be 27 days old.

From Ashburn (click to change) however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 5° above the horizon at dawn.

The Moon will be at mag -9.3, and Mercury at mag -0.2, both in the constellation Pisces.

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 01h55m40s +06°33' Pisces -9.3 31'49"6
Mercury 01h55m40s +08°57' Pisces -0.2 6"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 23° from the Sun, which is in Aries at this time of year.

The circumstances of this event were computed using the DE405 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.
