Venus and 134340 Pluto will share the same right ascension, with Venus passing 0°20' to the north of 134340 Pluto.
From Seattle, the pair will become visible around 16:39 (PST), 14° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 2 hours and 30 minutes after the Sun at 18:47.
Venus will be at mag -4.7, and 134340 Pluto at mag 15.1, both in the constellation Sagittarius.
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 Venus 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 |
| Venus | 19h50m40s | -22°24' | Sagittarius | -4.7 | 47"3 |
| 134340 Pluto | 19h50m40s | -22°44' | Sagittarius | 15.1 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 34° from the Sun, which is in Ophiuchus at this time of year.
