Conjunction of Venus and Saturn

Venus and Saturn will share the same right ascension, with Venus passing 37' to the south 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 02:45 (PDT) – 3 hours and 47 minutes before the Sun – and reaching an altitude of 36° above the south-eastern horizon before fading from view as dawn breaks at around 05:58.

Venus will be at mag -4.4, and Saturn at mag 0.7, both in the constellation Virgo.

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 Venus 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
Venus 12h48m20s 3°23'S Virgo -4.4 22"5
Saturn 12h48m20s 2°46'S Virgo 0.7 16"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 46° from the Sun, which is in Libra at this time of year.
