Conjunction of Mars and Mercury

From the Conjunctions feed


Mars and Mercury will share the same right ascension, with Mars passing 46' to the south of Mercury.

From Fairfield however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be 5° below the horizon at dawn.

Mars will be at mag 1.2, and Mercury at mag 2.6, both in the constellation Pisces.

The pair will be a little too widely separated to fit comfortably 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 Mars and Mercury 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
Mars 00h49m30s 4°25'N Pisces 1.2 4"0
Mercury 00h49m30s 5°12'N Pisces 2.6 11"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 15° from the Sun, which is in Aries 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.
