Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 6°33' to the south of Mars. The Moon will be 27 days old.

From Fairfield , the pair will be visible in the dawn sky, rising at 03:34 (EST) – 3 hours and 5 minutes before the Sun – and reaching an altitude of 25° above the eastern horizon before fading from view as dawn breaks at around 05:53.

The Moon will be at mag -10.0, and Mars at mag 1.7, both in the constellation Leo.

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 09h50m00s 7°52'N Leo -10.0 31'01"9
Mars 09h50m00s 14°26'N Leo 1.7 4"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 34° from the Sun, which is in Virgo at this time of year.
