The Moon and Mars will make a close approach, passing within 1°23' of each other. The Moon will be 24 days old.

From Fairfield , the pair will be visible in the dawn sky, rising at 01:54 (EST) and reaching an altitude of 31° above the southern horizon before fading from view as dawn breaks at around 06:25.

The Moon will be at mag -11.5; and Mars will be at mag 1.1. Both objects will lie in the constellation Libra.

They will be too widely separated to fit 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 15h22m30s 16°04'S Libra -11.5 30'32"7
Mars 15h21m30s 17°26'S Libra 1.1 5"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 72° from the Sun, which is in Capricornus at this time of year.
