Neptune and 1 Ceres will share the same right ascension, with Neptune passing 8°16' to the north of 1 Ceres.
A graph of the angular separation between Neptune 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|
The coordinates above are given in J2000.0. The pair will be at an angular separation of 47° from the Sun, which is in Aries at this time of year.
