Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 2°17' to the north of Mars. The Moon will be 7 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 19:50 (EST), 67° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 02:16.

The Moon will be at mag -11.7, and Mars at mag 0.9, both in the constellation Gemini.

The pair will be too widely separated to fit within the field of view of a telescope, but will 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 06h05m10s 27°49'N Gemini -11.7 29'53"1
Mars 06h05m10s 25°32'N Gemini 0.9 6"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 83° from the Sun, which is in Pisces at this time of year.
