The Moon and Mars will share the same right ascension, with the Moon passing 8°09' to the north of Mars. The Moon will be 9 days old.

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

From Ashburn, the pair will become visible around 20:28 (EDT) as the dusk sky fades, 26° above your southern horizon. They will then sink towards the horizon, setting at 00:35.

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 -12.0, and Mars at mag -0.6, both in the constellation Scorpius.

The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.

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 16h03m40s -15°30' Scorpius -12.0 29'42"8
Mars 16h03m40s -23°39' Scorpius -0.6 11"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 102° from the Sun, which is in Leo at this time of year.
