The Moon and Mercury will make a close approach, passing within 0°32' of each other. The Moon will be 2 days old.

From Fairfield however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 7° above 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 -9.2, and Mercury at mag -0.0, both in the constellation Leo.

The pair will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.

At around the same time, the two objects will also share the same right ascension – called a conjunction.

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 closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 10h35m40s +08°20' Leo -9.2 30'33"3
Mercury 10h36m10s +08°51' Leo -0.0 6"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 24° from the Sun, which is in Cancer at this time of year.
