Jupiter and 134340 Pluto will share the same right ascension, with Jupiter passing 0°41' to the north of 134340 Pluto.

From Ashburn, the pair will be visible in the morning sky, becoming accessible around 22:43, when they rise to an altitude of 7° above your south-eastern horizon. They will then reach its highest point in the sky at 02:40, 28° above your southern horizon. They will be lost to dawn twilight around 05:26, 17° above your south-western horizon.

Jupiter will be at mag -2.7, and 134340 Pluto at mag 15.0, both in the constellation Sagittarius.

The pair will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible through a pair of binoculars.

A graph of the angular separation between Jupiter 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
Jupiter 19h45m10s -21°31' Sagittarius -2.7 45"9
134340 Pluto 19h45m10s -22°13' Sagittarius 15.0 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 160° from the Sun, which is in Gemini at this time of year.
