The Moon and Mars will make a close approach, passing within 0°13' of each other. The Moon will be 15 days old.

From Fairfield, the pair will be visible in the morning sky, becoming accessible around 17:29, when they rise to an altitude of 7° above your north-eastern horizon. They will then reach its highest point in the sky at 00:20, 73° above your southern horizon. They will be lost to dawn twilight around 06:59, 9° above your north-western horizon.

The Moon will be at mag -12.7; and Mars will be at mag -1.4. Both objects will lie in the constellation Gemini.

They 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.

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 07h58m20s +25°13' Gemini -12.7 31'14"4
Mars 07h58m10s +25°00' Gemini -1.4 14"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 174° from the Sun, which is in Sagittarius at this time of year.
