Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 29' to the north 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 Cambridge , the pair will be visible in the evening sky, becoming accessible around 20:04 (EST), 14° above your south-eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 21:57, 19° above your southern horizon. They will continue to be observable until around 00:57, when they sink below 7° above your south-western horizon.

The Moon will be at mag -12.6, and Mars at mag -2.0, both in the constellation Sagittarius.

The pair will be close enough to fit within the field of view of a telescope, but will also 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 18h53m10s 27°52'S Sagittarius -12.6 32'39"4
Mars 18h53m10s 28°22'S Sagittarius -2.0 20"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 137° from the Sun, which is in Leo at this time of year.
