The Moon and Mercury will share the same right ascension, with the Moon passing 3°56' to the north of Mercury. The Moon will be 28 days old.

From Fairfield however, the pair will be visible from soon after it rises, at 04:07, until soon before it sets at 18:50. Always take extreme caution when trying to make daytime observations of the Moon while the Sun is above the horizon.

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 -8.6, and Mercury at mag -0.5, both in the constellation Taurus.

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 04h58m30s +24°50' Taurus -8.6 29'27"9
Mercury 04h58m30s +20°54' Taurus -0.5 6"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 19° from the Sun, which is in Gemini 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 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.
