Venus and Neptune will share the same right ascension, with Venus passing 0°04' to the south of Neptune.
From Fairfield, the pair will become visible around 17:21 (EDT) as the dusk sky fades, 30° above your south-western horizon. They will then sink towards the horizon, setting 3 hours and 20 minutes after the Sun at 20:21.
Venus will be at mag -4.1, and Neptune at mag 7.9, 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 39° from the Sun, which is in Capricornus at this time of year.
