Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 5°01' to the north of Mars. The Moon will be 25 days old.

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

From Los Angeles , the pair will be visible in the dawn sky, rising at 02:55 (PST) – 3 hours and 51 minutes before the Sun – and reaching an altitude of 28° above the south-eastern horizon before fading from view as dawn breaks at around 06:07.

The Moon will be at mag -11.1, and Mars at mag 1.3, both in the constellation Ophiuchus.

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 16h52m00s 17°16'S Ophiuchus -11.1 29'30"0
Mars 16h52m00s 22°18'S Ophiuchus 1.3 5"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 59° from the Sun, which is in Capricornus at this time of year.
