The planets Jupiter and Saturn will make a close approach, passing within 7°01' of each other.

From Jacksonville , the pair will be visible in the evening sky, becoming accessible around 19:42 (EDT), 78° above your south-eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 20:22, 82° above your southern horizon. They will continue to be observable until around 02:31, when they sink below 9° above your western horizon.

Jupiter will be at mag -2.4; and Saturn will be at mag -0.3. Both objects will lie in the constellation Gemini.

They will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.

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 07h27m50s 22°22'N Gemini -2.4 40"1
Saturn 06h57m30s 22°37'N Gemini -0.3 19"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 112° from the Sun, which is in Pisces at this time of year.
