Mercury and 1 Ceres will share the same right ascension, with Mercury passing 9°31' to the south of 1 Ceres.
From Cambridge however, the pair will not be readily observable since they will be very close to the Sun, at a separation of only 17° from it.
Mercury will be at mag 2.1 in the constellation Sextans, and 1 Ceres at mag 8.6 in the neighbouring constellation of 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 | 10h45m40s | 6°11'N | Sextans | 2.1 | 9"2 |
| 1 Ceres | 10h45m40s | 15°42'N | Leo | 8.6 | 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.
