Conjunction of Jupiter and Mercury

From the Conjunctions feed


Jupiter and Mercury will share the same right ascension, with Jupiter passing 7'04" to the north of Mercury.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Fairfield however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 2° above the horizon at dawn.

Jupiter will be at mag -2.0, and Mercury at mag -1.1, both in the constellation Taurus.

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 Jupiter 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
Jupiter 03h59m40s 19°50'N Taurus -2.0 32"0
Mercury 03h59m40s 19°43'N Taurus -1.1 5"3

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