The planets Jupiter and Saturn will make a close approach, passing within a mere 6.0 arcminutes of each other.
From Fairfield, the pair will be visible in the dawn sky, rising at 05:20 (EST) – 1 hour and 48 minutes before the Sun – and reaching an altitude of 13° above the south-eastern horizon before fading from view as dawn breaks around 06:49.
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.
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|
The coordinates above are given in J2000.0. The pair will be at an angular separation of 43° from the Sun, which is in Pisces 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.
