Venus and Jupiter will share the same right ascension, with Venus passing 0°19' to the north of Jupiter.
From Ashburn, the pair will be difficult to observe as they will appear no higher than 9° above the horizon. They will be visible in the dawn sky, rising at 05:16 (EST) – 1 hour and 16 minutes before the Sun – and reach an altitude of 9° above the eastern horizon before fading from view as dawn breaks at around 06:13.
Venus will be at mag -3.9, and Jupiter at mag -1.8, both in the constellation Cancer.
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 14° from the Sun, which is in Leo at this time of year.

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.
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.
