The planets Venus and Saturn will make a close approach, passing within a mere 41.7 arcminutes of each other.

From Jacksonville , the pair will be difficult to observe as they will appear no higher than 12° above the horizon. They will be visible in the dawn sky, rising at 05:33 (EDT) – 1 hour and 41 minutes before the Sun – and reaching an altitude of 12° above the south-eastern horizon before fading from view as dawn breaks at around 06:43.

Venus will be at mag -3.9; and Saturn will be at mag 0.4. Both objects will lie in the constellation Scorpius.

They will be a little too widely separated to fit comfortably within the field of view of a telescope, but will 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 Venus 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
Venus 16h12m50s 20°04'S Scorpius -3.9 10"8
Saturn 16h13m30s 19°23'S Scorpius 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 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.
