Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 7°46' to the south of Mars. The Moon will be 12 days old.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Fairfield , the pair will be visible in the evening sky, becoming accessible around 20:03 (EST), 41° above your south-eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 22:21, 52° above your southern horizon. They will continue to be observable until around 03:50, when they sink below 8° above your western horizon.

The Moon will be at mag -12.7, and Mars at mag -0.8, 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 Mars 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 11h45m30s 3°54'S Virgo -12.7 33'05"2
Mars 11h45m30s 3°52'N Virgo -0.8 13"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 142° from the Sun, which is in Aries at this time of year.
