The Moon and Mars will share the same right ascension, with the Moon passing 4°31' to the north of Mars. The Moon will be 28 days old.

From Cambridge, the pair will be visible in the dawn sky, rising at 05:35 (EDT) – 1 hour and 36 minutes before the Sun – and reaching an altitude of 12° above the eastern horizon before fading from view as dawn breaks around 06:52.

The Moon will be at mag -9.1, and Mars at mag 1.8, both in the constellation Virgo.

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 12h53m50s -00°18' Virgo -9.1 33'03"0
Mars 12h53m50s -04°50' Virgo 1.8 3"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 20° from the Sun, which is in Virgo at this time of year.
