1 Ceres and 134340 Pluto will share the same right ascension, with 1 Ceres passing 28" to the north of 134340 Pluto.
From South El Monte , the pair will be visible between 19:51 and 01:50. They will become accessible at around 19:51, when they rise to an altitude of 21° above your south-eastern horizon. They will reach their highest point in the sky at 22:51, 37° above your southern horizon. They will become inaccessible at around 01:50 when they sink below 21° above your south-western horizon.
1 Ceres will be at mag 8.0, and 134340 Pluto at mag 15.9, both in the constellation Aquarius.
The pair will be close enough to fit within the field of view of a telescope, but will also be visible through a pair of binoculars.
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 | 23h35m50s | 18°48'S | Aquarius | 8.0 | 0"0 |
| 134340 Pluto | 23h35m50s | 18°49'S | Aquarius | 15.9 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 143° from the Sun, which is in Virgo at this time of year.
