Mercury and 1 Ceres will share the same right ascension, with Mercury passing 6°55' to the south of 1 Ceres.
From Fairfield however, the pair will not be readily observable since they will be very close to the Sun, at a separation of only 12° from it.
Mercury will be at mag -0.7, and 1 Ceres at mag 8.5, both in the constellation Leo.
A graph of the angular separation between Mercury 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 |
| Mercury | 10h58m10s | 7°53'N | Leo | -0.7 | 5"0 |
| 1 Ceres | 10h58m10s | 14°48'N | Leo | 8.5 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 12° from the Sun, which is in Leo at this time of year.
