Venus and Jupiter will share the same right ascension, with Venus passing 2°26' to the north of Jupiter.
From Fairfield, the pair will be visible in the dawn sky, rising at 04:05 (EDT) – 3 hours and 7 minutes before the Sun – and reaching an altitude of 21° above the south-eastern horizon before fading from view as dawn breaks around 06:52.
Venus will be at mag -4.3, and Jupiter at mag -1.9, both in the constellation Ophiuchus.
The pair will be too widely separated to fit within the field of view of a telescope, but will 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 46° from the Sun, which is in Capricornus at this time of year.
