The Moon and Mercury will share the same right ascension, with the Moon passing 6°02' to the north of Mercury. The Moon will be 1 days old.

From Seattle however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be 2° below the horizon at dusk.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

The Moon will be at mag -8.2, and Mercury at mag 1.6, both in the constellation Virgo.

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 11h47m00s +02°44' Virgo -8.2 30'03"0
Mercury 11h47m00s -03°17' Virgo 1.6 9"9

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

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.


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.
