The Moon and Mars will make a close approach, passing within a mere 39.6 arcminutes of each other. From some parts of the world, the Moon will pass in front of Mars, creating a lunar occultation. The Moon will be 16 days old.

From Columbus , the pair will be visible in the morning sky, becoming accessible around 20:42, when they reach an altitude of 7° above your eastern horizon. They will then reach their highest point in the sky at 02:21, 56° above your southern horizon. They will be lost to dawn twilight around 07:10, 17° above your western horizon.

The Moon will be at mag -12.5; and Mars will be at mag -2.5. Both objects will lie in the constellation Pisces.

They 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.

At around the same time, the pair 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 pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 01h35m50s 5°24'N Pisces -12.5 29'24"1
Mars 01h34m40s 6°00'N Pisces -2.5 22"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 165° from the Sun, which is in Virgo at this time of year.
