Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 4°52' to the north of Mars. The Moon will be 24 days old.

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

From South El Monte , the pair will be visible in the dawn sky, rising at 01:55 (PDT) – 3 hours and 40 minutes before the Sun – and reaching an altitude of 36° above the south-eastern horizon before fading from view as dawn breaks at around 05:00.

The Moon will be at mag -11.5 in the constellation Pisces, and Mars at mag 0.5 in the neighbouring constellation of Cetus.

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 00h42m50s 7°22'N Pisces -11.5 32'27"2
Mars 00h42m50s 2°30'N Cetus 0.5 7"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 69° from the Sun, which is in Taurus at this time of year.
