1 Ceres and 136199 Eris will share the same right ascension, with 1 Ceres passing 2°56' to the north of 136199 Eris.
1 Ceres will be at mag 9.2, and 136199 Eris at mag 18.8, both in the constellation Cetus.
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 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|
The coordinates above are given in J2000.0. The pair will be at an angular separation of 70° from the Sun, which is in Gemini at this time of year.
