Venus and Neptune will share the same right ascension, with Venus passing 0°00' to the south of Neptune.
From Ashburn, the pair will become visible around 18:05 (EDT) as the dusk sky fades, 21° above your south-western horizon. They will then sink towards the horizon, setting 2 hours and 12 minutes after the Sun at 20:01.
Venus will be at mag -4.0, and Neptune at mag 8.0, both in the constellation Aquarius.
The pair will be close enough to fit within the field of view of a telescope, but will also be visible through a pair of binoculars.
A graph of the angular separation between Venus and Neptune 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 27° from the Sun, which is in Capricornus 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.
