Conjunction of Mercury and Mars

From the Conjunctions feed


Mercury and Mars will share the same right ascension, with Mercury passing 18' to the north of Mars.

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 4° above the horizon at dusk.

Mercury will be at mag -1.0, and Mars at mag 1.2, both in the constellation Aquarius.

The pair will be close enough to fit within the field of view of a telescope, but will also be visible to the naked eye or through a pair of binoculars.

A graph of the angular separation between Mercury 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
Mercury 22h29m30s 10°13'S Aquarius -1.0 5"8
Mars 22h29m30s 10°31'S Aquarius 1.2 4"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 15° 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.
