Conjunction of the Moon and Mars

From the Conjunctions feed


The Moon and Mars will share the same right ascension, with the Moon passing 5°37' to the north of Mars. The Moon will be 2 days old.

From Cambridge however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 10° above the horizon at dusk.

The Moon will be at mag -9.8, and Mars at mag 1.2, both in the constellation Sagittarius.

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 19h33m40s 17°15'S Sagittarius -9.8 32'55"3
Mars 19h33m40s 22°52'S Sagittarius 1.2 4"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 29° from the Sun, which is in Ophiuchus at this time of year.
