Venus and Jupiter will share the same right ascension, with Venus passing 0°11' to the south of Jupiter.
From Ashburn, the pair will be difficult to observe as they will appear no higher than 8° above the horizon. They will become visible at around 19:58 (EST) as the dusk sky fades, 8° above your western horizon. They will then sink towards the horizon, setting 1 hour and 6 minutes after the Sun at 20:46.
Venus will be at mag -3.9, and Jupiter at mag -1.7, both in the constellation Virgo.
The pair will be close enough to fit within the field of view of a telescope, but will also be visible to the naked eye or through a pair of binoculars.
A graph of the angular separation between Venus and Jupiter 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|
The coordinates above are given in J2000.0. The pair will be at an angular separation of 25° from the Sun, which is in Leo at this time of year.

The circumstances of this event were computed using the DE405 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.
