Conjunction of Jupiter and Saturn

Jupiter and Saturn will share the same right ascension, with Jupiter passing 57' to the north of Saturn.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From South El Monte , the pair will be visible in the dawn sky, rising at 03:01 (PDT) – 2 hours and 42 minutes before the Sun – and reaching an altitude of 25° above the eastern horizon before fading from view as dawn breaks at around 05:14.

Jupiter will be at mag -2.1, and Saturn at mag -0.0, both in the constellation Taurus.

The pair 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.

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

The positions of the two objects at the moment of conjunction will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Jupiter 04h48m30s 21°46'N Taurus -2.1 33"3
Saturn 04h48m30s 20°48'N Taurus -0.0 16"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 39° from the Sun, which is in Gemini at this time of year.
