Conjunction of Mercury and Saturn

From the Conjunctions feed


Mercury and Saturn will share the same right ascension, with Mercury passing 13' to the south of Saturn.

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 6° above the horizon at dawn.

Mercury will be at mag -0.6, and Saturn at mag -0.0, 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 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 05h22m40s 21°40'N Taurus -0.6 6"3
Saturn 05h22m40s 21°53'N Taurus -0.0 16"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 19° from the Sun, which is in Gemini 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.

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.
