Venus and 1 Ceres will share the same right ascension, with Venus passing 8'57" to the south of 1 Ceres.
From Cambridge however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 9° above the horizon at dawn.
Venus will be at mag -4.0, and 1 Ceres at mag 9.0, both in the constellation Ophiuchus.
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 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 | 17h22m50s | 21°47'S | Ophiuchus | -4.0 | 13"0 |
| 1 Ceres | 17h22m50s | 21°38'S | Ophiuchus | 9.0 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 34° from the Sun, which is in Sagittarius at this time of year.
