Venus and Saturn will make a close approach, passing within 3°28' of each other.
From Fairfield, the pair will be difficult to observe as they will appear no higher than 15° above the horizon. They will become visible around 19:13 (EDT) as the dusk sky fades, 15° above your south-western horizon. They will then sink towards the horizon, setting 1 hour and 53 minutes after the Sun at 20:48.
Venus will be at mag -4.1, and Saturn at mag 0.5, both in the constellation 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 Venus and Saturn around the time of closest approach is available here.
The positions of the two objects 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 42° from the Sun, which is in Virgo at this time of year.

The circumstances of this event were computed using the DE405 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.
