1 Ceres will pass close to the Sun in the sky as its orbit carries it around the far side of the solar system from the Earth.
At closest approach, 1 Ceres will appear at a separation of only 2°03' from the Sun, making it totally unobservable for several weeks while it is lost in the Sun's glare.
At around the same time, 1 Ceres will also be at its most distant from the Earth – receding to a distance of 3.85 AU – since the two planets will lie on opposite sides of the solar system.
Over following weeks and months, 1 Ceres will re-emerge to the west of the Sun, gradually becoming visible for ever-longer periods in the pre-dawn sky. After around six months, it will reach opposition, when it will be visible for virtually the whole night. A chart of the path of 1 Ceres across the sky in 2028 can be found here, and a chart of its rising and setting times here.
The position of 1 Ceres at the moment it passes solar conjunction will be:
| Object | Right Ascension | Declination | Constellation | Angular Size |
| 1 Ceres | 18h23m10s | 25°23'S | Sagittarius | 0.0" |
| Sun | 18h22m | 23°19'S | Sagittarius | 32'31" |
The coordinates above are given in J2000.0.
