The Moon and Mars will make a close approach, passing within 1°16' of each other. The Moon will be 5 days old.

From Fairfield , the pair will become visible at around 21:09 (EST), 39° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 00:46.

The Moon will be at mag -11.4; and Mars will be at mag 1.3. Both objects will lie in the constellation Leo.

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 09h37m20s 17°03'N Leo -11.4 30'53"9
Mars 09h35m10s 15°52'N Leo 1.3 5"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 70° from the Sun, which is in Taurus at this time of year.
