The Moon and Mars will share the same right ascension, with the Moon passing 2°04' to the north of Mars. The Moon will be 6 days old.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Fairfield, the pair will become visible around 20:11 (EDT) as the dusk sky fades, 62° above your south-western horizon. They will then sink towards the horizon, setting at 02:05.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

The Moon will be at mag -11.7, and Mars at mag 1.0, both in the constellation Cancer.

The pair 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.

A graph of the angular separation between the Moon and Mars around the time of closest approach is available here.

The positions of the two objects at the moment of conjunction will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 08h38m00s +22°34' Cancer -11.7 31'02"8
Mars 08h38m00s +20°29' Cancer 1.0 6"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 82° from the Sun, which is in Aries at this time of year.
