Venus and Saturn will make a close approach, passing within 3°28' of each other.
From Ashburn (click to change), the pair will be difficult to observe as they will appear no higher than 17° above the horizon. They will become visible at around 19:29 (EST) as the dusk sky fades, 17° above your south-western horizon. They will then sink towards the horizon, setting 1 hour and 57 minutes after the Sun at 21:08.
At the moment of closest approach, Venus will be at mag -4.6, and Saturn at mag 1.1, both in the constellation Libra.
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.
The precise positions of Venus and Saturn at the moment of closest approach will be as follows:
The coordinates above are given in J2000.0. The pair will be at an angular separation of 42° from the Sun, which is in Virgo at this time of year.
The circumstances of this event were computed from the DE405 ephemeris published by the Jet Propulsion Laboratory (JPL).
The positions of deep sky objects in conjunctions are taken from the NGC2000.0 catalogue.
