Jupiter and 134340 Pluto will share the same right ascension, with Jupiter passing 44' to the north of 134340 Pluto.

From Fairfield , the pair will be visible in the dawn sky, rising at 02:47 (EDT) – 3 hours and 33 minutes before the Sun – and reaching an altitude of 23° above the southern horizon before fading from view as dawn breaks around 06:03.

Jupiter will be at mag -2.2, and 134340 Pluto at mag 15.1, 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 19h48m00s -21°11' Sagittarius -2.2 37"1
134340 Pluto 19h48m00s -21°56' Sagittarius 15.1 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 84° from the Sun, which is in Pisces at this time of year.

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
