Conjunction of Mercury and Saturn

From the Conjunctions feed


Mercury and Saturn will share the same right ascension, with Mercury passing 4°15' to the south of Saturn.

From Jacksonville however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 7° above the horizon at dusk.

Mercury will be at mag -0.3 in the constellation Scorpius, and Saturn at mag 0.4 in the neighbouring constellation of Libra.

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 Mercury and Saturn 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 15h50m50s 22°33'S Scorpius -0.3 5"6
Saturn 15h50m50s 18°17'S Libra 0.4 15"2

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

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
