1 Ceres and 136199 Eris will share the same right ascension, with 1 Ceres passing 43' to the north of 136199 Eris.
From Fairfield , the pair will be visible between 18:23 and 02:02. They will become accessible at around 18:23, when they rise to an altitude of 21° above your south-eastern horizon. They will reach their highest point in the sky at 22:13, 46° above your southern horizon. They will become inaccessible at around 02:02 when they sink below 21° above your south-western horizon.
1 Ceres will be at mag 7.7, and 136199 Eris at mag 18.7, both in the constellation Cetus.
The pair will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible through a pair of binoculars.
A graph of the angular separation between 1 Ceres and 136199 Eris 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 |
| 1 Ceres | 01h42m50s | 1°59'S | Cetus | 7.7 | 0"0 |
| 136199 Eris | 01h42m50s | 2°43'S | Cetus | 18.7 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 152° from the Sun, which is in Libra at this time of year.
