Conjunction of the Moon and Mercury

From the Conjunctions feed


The Moon and Mercury will share the same right ascension, with the Moon passing 2°07' to the north of Mercury. The Moon will be 28 days old.

From Fairfield however, the pair will not be readily observable since they will be very close to the Sun, at a separation of only 12° from it.

The Moon will be at mag -7.9, and Mercury at mag 2.8, both in the constellation Aquarius.

The pair will be too widely separated to fit within the field of view of a telescope, but will be visible 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 22h34m20s 3°52'S Aquarius -7.9 31'36"5
Mercury 22h34m20s 6°00'S Aquarius 2.8 10"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 12° from the Sun, which is in Aquarius at this time of year.

Warning

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.
