Venus and 1 Ceres will share the same right ascension, with Venus passing 8°10' to the south of 1 Ceres.
From Ashburn, the pair will become visible at around 20:49 (EDT) as the dusk sky fades, 25° above your western horizon. They will then sink towards the horizon, setting 2 hours and 35 minutes after the Sun at 23:04.
Venus will be at mag -4.1, and 1 Ceres at mag 8.8, both in the constellation Leo.
A graph of the angular separation between Venus and 1 Ceres 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 43° from the Sun, which is in Cancer at this time of year.
