Venus and 1 Ceres will share the same right ascension, with Venus passing 3°01' to the south of 1 Ceres.
From Fairfield , the pair will be visible in the dawn sky, rising at 03:18 (EDT) – 3 hours and 58 minutes before the Sun – and reaching an altitude of 26° above the south-eastern horizon before fading from view as dawn breaks at around 06:04.
Venus will be at mag -4.5, and 1 Ceres at mag 8.9, both in the constellation Libra.
The pair will be too widely separated to fit within the field of view of a telescope, but will be visible through a pair of binoculars.
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 |
| Venus | 15h18m30s | 14°44'S | Libra | -4.5 | 26"9 |
| 1 Ceres | 15h18m30s | 11°42'S | Libra | 8.9 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 46° from the Sun, which is in Sagittarius at this time of year.
