Venus and Neptune will share the same right ascension, with Venus passing 18' to the south of Neptune.
Venus will be at mag -3.9, 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 32° from the Sun, which is in Pisces at this time of year.
