Conjunction of the Moon and Mars

From the Conjunctions feed


The Moon and Mars will share the same right ascension, with the Moon passing 42' to the north of Mars. The Moon will be 1 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 difficult to observe as they will appear no higher than 14° above the horizon. They will become visible at around 19:59 (EDT), 14° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 2 hours and 8 minutes after the Sun at 21:23.

The Moon will be at mag -9.5, and Mars at mag 1.4, both in the constellation Aries.

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.

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 02h24m10s 15°08'N Aries -9.5 32'49"7
Mars 02h24m10s 14°26'N Aries 1.4 4"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 25° from the Sun, which is in Pisces at this time of year.
