Venus and 1 Ceres will share the same right ascension, with Venus passing 3°21' to the south of 1 Ceres.
From South El Monte , the pair will become visible at around 21:07 (PDT), 25° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 3 hours and 29 minutes after the Sun at 23:26.
Venus will be at mag -4.2, and 1 Ceres at mag 8.8, both in the constellation Gemini.
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 | 07h22m10s | 24°40'N | Gemini | -4.2 | 18"3 |
| 1 Ceres | 07h22m10s | 28°02'N | Gemini | 8.8 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 43° from the Sun, which is in Taurus at this time of year.
