Venus and 1 Ceres will share the same right ascension, with Venus passing 12' to the south of 1 Ceres.
From South El Monte , the pair will be visible in the dawn sky, rising at 03:32 (PDT) – 3 hours and 25 minutes before the Sun – and reaching an altitude of 23° above the south-eastern horizon before fading from view as dawn breaks at around 05:54.
Venus will be at mag -4.4, and 1 Ceres at mag 8.9, 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 | 16h38m00s | 18°32'S | Ophiuchus | -4.4 | 24"2 |
| 1 Ceres | 16h38m00s | 18°19'S | Ophiuchus | 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.
