The Moon, Mars and Saturn will make a close approach, passing within 5°08' of each other. The Moon will be 11 days old.

From South El Monte , the trio will be visible in the evening sky, becoming accessible around 18:46 (PDT), 18° above your south-eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 22:27, 41° above your southern horizon. They will continue to be observable until around 03:07, when they sink below 7° above your south-western horizon.

The Moon will be at mag -12.5; Mars will be at mag -2.1; and Saturn will be at mag 0.4. The trio will lie in the constellation Aquarius.

They 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.

At around the same time, the trio will also share the same right ascension – called a conjunction.

A graph of the angular separation between the Moon and Mars around the time of closest approach is available here.

The positions of the trio at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 22h19m50s 9°36'S Aquarius -12.5 29'58"7
Mars 22h29m00s 14°13'S Aquarius -2.1 20"7
Saturn 22h20m10s 12°19'S Aquarius 0.4 18"5

The coordinates above are given in J2000.0. The trio will be at an angular separation of 143° from the Sun, which is in Virgo at this time of year.
