The Moon and Mars will make a close approach, passing within 2°27' of each other. The Moon will be 3 days old.

From Cambridge, the pair will be difficult to observe as they will appear no higher than 12° above the horizon. They will become visible around 19:45 (EDT) as the dusk sky fades, 12° above your western horizon. They will then sink towards the horizon, setting 1 hour and 29 minutes after the Sun at 20:54.

The Moon will be at mag -10.2, and Mars at mag 1.6, 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.

At around the same time, the two objects 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 two objects at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 12h40m10s -06°38' Virgo -10.2 29'54"3
Mars 12h44m50s -04°28' Virgo 1.6 4"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 38° from the Sun, which is in Leo at this time of year.
