Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 51' to the south of Mars. The Moon will be 11 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 evening sky, becoming accessible around 19:59 (PDT), 57° above your south-eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 20:57, 61° above your southern horizon. They will continue to be observable until around 02:26, when they sink below 9° above your western horizon.

The Moon will be at mag -12.3, and Mars at mag -0.3, 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 11h28m20s 4°12'N Leo -12.3 30'46"6
Mars 11h28m20s 5°04'N Leo -0.3 11"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 121° from the Sun, which is in Aries at this time of year.
