Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 7°29' to the north of Mars. The Moon will be 15 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 be visible between 19:50 and 06:11. They will become accessible at around 19:50, when they rise to an altitude of 7° above your eastern horizon. They will reach their highest point in the sky at 01:01, 46° above your southern horizon. They will become inaccessible at around 06:11 when they sink below 7° above your western horizon.

The Moon will be at mag -12.8 in the constellation Pisces, and Mars at mag -2.8 in the neighbouring constellation of Cetus.

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 00h29m10s 5°33'N Pisces -12.8 33'17"7
Mars 00h29m10s 1°55'S Cetus -2.8 23"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 174° from the Sun, which is in Virgo at this time of year.
