The Moon and Mars will make a close approach, passing within 4°27' of each other. The Moon will be 11 days old.

From Cambridge , the pair will be visible in the evening sky, becoming accessible around 16:33 (EDT), 28° above your eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 20:21, 53° above your southern horizon. They will continue to be observable until around 02:00, when they sink below 7° above your western horizon.

The Moon will be at mag -12.4 in Cetus; and Mars will be at mag -1.3 in Pisces.

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 01h06m20s 1°56'N Cetus -12.4 29'27"6
Mars 00h58m50s 5°59'N Pisces -1.3 15"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 131° from the Sun, which is in Scorpius at this time of year.
