Neptune and 1 Ceres will share the same right ascension, with Neptune passing 7°39' to the north 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 13° from it.
Neptune will be at mag 8.0, and 1 Ceres at mag 9.1, both in the constellation Aquarius.
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 |
| Neptune | 22h42m20s | 9°02'S | Aquarius | 8.0 | 2"2 |
| 1 Ceres | 22h42m20s | 16°41'S | Aquarius | 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 Capricornus at this time of year.
