Saturn and 1 Ceres will share the same right ascension, with Saturn passing 1°42' to the south of 1 Ceres.
From Fairfield , the pair will be visible in the dawn sky, rising at 03:01 (EDT) – 3 hours and 54 minutes before the Sun – and reaching an altitude of 22° above the south-eastern horizon before fading from view as dawn breaks at around 05:48.
Saturn will be at mag 0.3, and 1 Ceres at mag 8.9, both in the constellation Ophiuchus.
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 Saturn 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 |
| Saturn | 17h14m20s | 21°30'S | Ophiuchus | 0.3 | 15"8 |
| 1 Ceres | 17h14m20s | 19°48'S | Ophiuchus | 8.9 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 61° from the Sun, which is in Capricornus at this time of year.
