1 Ceres and 134340 Pluto will share the same right ascension, with 1 Ceres passing 9°39' to the south of 134340 Pluto.
From South El Monte , the pair will become visible at around 19:10 (PDT), 29° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 22:13.
1 Ceres will be at mag 9.1, and 134340 Pluto at mag 14.8, both in the constellation Sagittarius.
A graph of the angular separation between 1 Ceres and 134340 Pluto 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 |
| 1 Ceres | 18h12m50s | 28°21'S | Sagittarius | 9.1 | 0"0 |
| 134340 Pluto | 18h12m50s | 18°42'S | Sagittarius | 14.8 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 64° from the Sun, which is in Virgo at this time of year.
