Conjunction of the Moon and Mercury

From the Conjunctions feed


The Moon and Mercury will share the same right ascension, with the Moon passing 33' to the south of Mercury. The Moon will be 1 days old.

From Cambridge however, the pair will not be readily observable since they will be very close to the Sun, at a separation of only 14° from it.

The Moon will be at mag -8.1, and Mercury at mag 3.0, both in the constellation Cancer.

The pair will be a little too widely separated to fit comfortably 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 08h50m10s 12°48'N Cancer -8.1 30'45"4
Mercury 08h50m10s 13°21'N Cancer 3.0 11"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 14° from the Sun, which is in Gemini 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.
