Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 4°11' to the north of Mars. The Moon will be 19 days old.

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

From Columbus , the pair will be visible in the morning sky, becoming accessible around 01:35, when they reach an altitude of 9° above your south-eastern horizon. They will then reach their highest point in the sky at 05:26, 29° above your southern horizon. They will be lost to dawn twilight around 06:57, 25° above your south-western horizon.

The Moon will be at mag -12.3, and Mars at mag -0.4, both in the constellation Scorpius.

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 16h19m10s 16°16'S Scorpius -12.3 29'43"5
Mars 16h19m10s 20°27'S Scorpius -0.4 11"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 122° from the Sun, which is in Pisces at this time of year.
