Mercury and 1 Ceres will share the same right ascension, with Mercury passing 6°08' to the north of 1 Ceres.
From South El Monte however, the pair will not be readily observable since they will be very close to the Sun, at a separation of only 18° from it.
Mercury will be at mag -0.7 in the constellation Pisces, and 1 Ceres at mag 9.1 in the neighbouring constellation of Cetus.
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 | 00h55m50s | 3°45'N | Pisces | -0.7 | 5"2 |
| 1 Ceres | 00h55m50s | 2°22'S | Cetus | 9.1 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 14° from the Sun, which is in Pisces at this time of year.
