Mars and 134340 Pluto will share the same right ascension, with Mars passing 8°14' to the south of 134340 Pluto.
From Fairfield however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 20° above the horizon at dawn.
Mars will be at mag 1.4 in the constellation Ophiuchus, and 134340 Pluto at mag 14.7 in the neighbouring constellation of Serpens Cauda.
A graph of the angular separation between Mars 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 |
| Mars | 17h34m00s | 23°28'S | Ophiuchus | 1.4 | 4"5 |
| 134340 Pluto | 17h34m00s | 15°14'S | Serpens Cauda | 14.7 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 45° from the Sun, which is in Capricornus at this time of year.
