Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 2°55' to the south of Mars. The Moon will be 22 days old.

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

From Columbus , the pair will be visible in the dawn sky, rising at 02:40 (EDT) – 3 hours and 46 minutes before the Sun – and reaching an altitude of 23° above the southern horizon before fading from view as dawn breaks at around 05:53.

The Moon will be at mag -11.8, and Mars at mag 0.6, both in the constellation Sagittarius.

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 18h57m20s 26°11'S Sagittarius -11.8 31'23"3
Mars 18h57m20s 23°16'S Sagittarius 0.6 7"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 81° from the Sun, which is in Pisces at this time of year.
