Mars and 1 Ceres will share the same right ascension, with Mars passing 7°26' to the north of 1 Ceres.
From South El Monte however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 13° above the horizon at dusk.
Mars will be at mag 1.1, and 1 Ceres at mag 9.3, both in the constellation Capricornus.
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 | 21h52m10s | 14°02'S | Capricornus | 1.1 | 4"5 |
| 1 Ceres | 21h52m10s | 21°28'S | Capricornus | 9.3 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 35° from the Sun, which is in Sagittarius at this time of year.
