Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 9°44' to the south of Mars. The Moon will be 18 days old.

From Fairfield , the pair will be visible in the morning sky, becoming accessible around 20:26, when they reach an altitude of 8° above your eastern horizon. They will then reach their highest point in the sky at 02:07, 56° above your southern horizon. They will be lost to dawn twilight around 06:33, 22° above your western horizon.

The Moon will be at mag -12.7, and Mars at mag -0.8, both in the constellation Leo.

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 11h33m10s 2°26'S Leo -12.7 32'23"5
Mars 11h33m10s 7°18'N Leo -0.8 12"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 145° from the Sun, which is in Capricornus at this time of year.
