Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 17' to the south of Mars. The Moon will be 5 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 become visible at around 17:39 (EDT), 46° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 22:18.

The Moon will be at mag -11.4, and Mars at mag 0.9, both in the constellation Pisces.

The pair will be close enough to fit within the field of view of a telescope, but will also be visible to the naked eye or through a pair of binoculars.

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 00h31m40s 3°00'N Pisces -11.4 32'16"6
Mars 00h31m40s 3°18'N Pisces 0.9 5"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 63° from the Sun, which is in Capricornus at this time of year.
