Jupiter and Neptune will share the same right ascension, with Jupiter passing 6'28" to the north of Neptune.

From San Diego however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 1° above the horizon at dawn.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

Jupiter will be at mag -2.1, and Neptune at mag 8.0, both in the constellation Aquarius.

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 Jupiter and Neptune 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 23h38m30s 3°26'S Aquarius -2.1 33"0
Neptune 23h38m30s 3°32'S Aquarius 8.0 2"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 28° 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.
