Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 41' to the north of Mars. The Moon will be 17 days old.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Cambridge , the pair will be visible in the morning sky, becoming accessible around 20:13, when they reach an altitude of 8° above your eastern horizon. They will then reach their highest point in the sky at 02:27, 64° above your southern horizon. They will be lost to dawn twilight around 06:47, 29° above your western horizon.

The Moon will be at mag -12.5, and Mars at mag -0.7, 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 09h58m40s 17°13'N Leo -12.5 29'45"9
Mars 09h58m40s 16°31'N Leo -0.7 12"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 142° from the Sun, which is in Sagittarius at this time of year.
