The planets Jupiter and Saturn will make a close approach, passing within a mere 14.5 arcminutes of each other.

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 17:15 (EDT), 11° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 1 hour and 52 minutes after the Sun at 18:30.

Jupiter will be at mag -2.0; and Saturn will be at mag 0.6. Both objects will lie in the constellation Capricornus.

They 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.

At around the same time, the pair will also share the same right ascension – called a conjunction.

A graph of the angular separation between Jupiter and Saturn around the time of closest approach is available here.

The positions of the pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Jupiter 21h11m10s 16°57'S Capricornus -2.0 32"4
Saturn 21h11m20s 17°11'S Capricornus 0.6 15"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 23° from the Sun, which is in Sagittarius 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.
