Conjunction of the Moon and Mars

From the Conjunctions feed


The Moon and Mars will share the same right ascension, with the Moon passing 2°30' to the north of Mars. The Moon will be 29 days old.

From South El Monte however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be 1° below the horizon at dawn.

The Moon will be at mag -8.0, and Mars at mag 1.2, both in the constellation Capricornus.

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 20h18m40s 18°08'S Capricornus -8.0 33'03"0
Mars 20h18m40s 20°38'S Capricornus 1.2 3"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 12° from the Sun, which is in Capricornus at this time of year.

Warning

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.
