The Moon and Mars will make a close approach, passing within a mere 53.6 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 15 days old.

From Columbus , the pair will be visible between 17:48 and 07:29. They will become accessible at around 17:48, when they rise to an altitude of 7° above your north-eastern horizon. They will reach their highest point in the sky at 00:38, 76° above your southern horizon. They will become inaccessible at around 07:29 when they sink below 7° above your north-western horizon.

The Moon will be at mag -12.8; and Mars will be at mag -1.6. Both objects will lie in the constellation Gemini.

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 06h12m40s 27°38'N Gemini -12.8 32'52"8
Mars 06h12m20s 26°44'N Gemini -1.6 15"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 175° from the Sun, which is in Sagittarius at this time of year.
