Mars and 1 Ceres will share the same right ascension, with Mars passing 2°04' to the south of 1 Ceres.
From Cambridge , the pair will be visible in the dawn sky, rising at 00:51 (EST) and reaching an altitude of 25° above the southern horizon before fading from view as dawn breaks at around 04:55.
Mars will be at mag -0.3, and 1 Ceres at mag 8.3, both in the constellation Sagittarius.
The pair will be too widely separated to fit within the field of view of a telescope, but will be visible through a pair of binoculars.
A graph of the angular separation between Mars 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 |
| Mars | 18h09m20s | 23°42'S | Sagittarius | -0.3 | 10"7 |
| 1 Ceres | 18h09m20s | 21°38'S | Sagittarius | 8.3 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 110° from the Sun, which is in Pisces at this time of year.
