Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 34' to the south of Mars. The Moon will be 23 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 dawn sky, rising at 23:51 (EDT) and reaching an altitude of 58° above the southern horizon before fading from view as dawn breaks at around 06:05.

The Moon will be at mag -11.7, and Mars at mag 1.0, 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.

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 10h48m50s 9°07'N Leo -11.7 30'50"5
Mars 10h48m50s 9°41'N Leo 1.0 6"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 81° from the Sun, which is in Scorpius at this time of year.
