Conjunction of Jupiter and Saturn

Jupiter and Saturn will share the same right ascension, with Jupiter passing 1°08' 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 become visible at around 19:43 (PDT), 31° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 3 hours and 4 minutes after the Sun at 22:21.

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

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 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 03h53m40s 19°38'N Taurus -2.1 33"4
Saturn 03h53m40s 18°29'N Taurus 0.0 16"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 39° 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.
