Uranus and 1 Ceres will share the same right ascension, with Uranus passing 6°26' 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 2° below the horizon at dawn.
Uranus will be at mag 5.9 in the constellation Aries, and 1 Ceres at mag 9.2 in the neighbouring constellation of Cetus.
A graph of the angular separation between Uranus 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 |
| Uranus | 02h40m00s | 15°09'N | Aries | 5.9 | 3"4 |
| 1 Ceres | 02h40m00s | 8°42'N | Cetus | 9.2 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 32° from the Sun, which is in Taurus at this time of year.
