Venus and 1 Ceres will share the same right ascension, with Venus passing 8°34' to the north of 1 Ceres.
From South El Monte however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 7° above the horizon at dawn.
Venus will be at mag -4.4, and 1 Ceres at mag 9.3, both in the constellation Capricornus.
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 | 21h51m30s | 11°29'S | Capricornus | -4.4 | 24"9 |
| 1 Ceres | 21h51m30s | 20°03'S | Capricornus | 9.3 | 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 Pisces at this time of year.
