Neptune and 1 Ceres will share the same right ascension, with Neptune passing 8°16' to the north of 1 Ceres.

From Fairfield however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 0° above the horizon at dawn.

Neptune will be at mag 7.9 in the constellation Pisces, and 1 Ceres at mag 9.5 in the neighbouring constellation of Cetus.

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 00h05m30s -00°47' Pisces 7.9 2"2
1 Ceres 00h05m30s -09°04' Cetus 9.5 0"0

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.
