Conjunction of Jupiter and Mercury

From the Conjunctions feed


Jupiter and Mercury will share the same right ascension, with Jupiter passing 2°47' to the south of Mercury.

From Fairfield , the pair will be difficult to observe as they will appear no higher than 11° above the horizon. They will become visible at around 20:35 (EDT), 11° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 1 hour and 40 minutes after the Sun at 21:46.

Jupiter will be at mag -1.9, and Mercury at mag -0.2, both in the constellation Taurus.

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 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 05h03m10s 22°25'N Taurus -1.9 32"0
Mercury 05h03m10s 25°13'N Taurus -0.2 7"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 21° from the Sun, which is in Taurus at this time of year.
