Mars and 134340 Pluto will share the same right ascension, with Mars passing 3°19' to the south of 134340 Pluto.
From Columbus , the pair will become visible at around 19:51 (EST), 26° above your southern horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 23:31.
Mars will be at mag 0.2, and 134340 Pluto at mag 15.0, 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 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 | 19h04m00s | 24°46'S | Sagittarius | 0.2 | 7"9 |
| 134340 Pluto | 19h04m00s | 21°27'S | Sagittarius | 15.0 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 78° from the Sun, which is in Virgo at this time of year.
