Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 28' to the south of Mars. The Moon will be 7 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 become visible at around 19:28 (PDT), 27° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 3 hours and 36 minutes after the Sun at 22:35.

The Moon will be at mag -11.5, and Mars at mag 0.4, both in the constellation Scorpius.

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 16h21m30s 23°53'S Scorpius -11.5 29'37"3
Mars 16h21m30s 23°24'S Scorpius 0.4 7"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 77° from the Sun, which is in Leo at this time of year.
