Jupiter and Neptune will share the same right ascension, with Jupiter passing 24' to the south of Neptune.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Cambridge , the pair will be visible in the dawn sky, rising at 01:12 (EDT) and reaching an altitude of 23° above the south-eastern horizon before fading from view as dawn breaks at around 03:49.

Jupiter will be at mag -2.4, and Neptune at mag 7.9, both in the constellation Capricornus.

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:

The coordinates above are given in J2000.0. The pair will be at an angular separation of 98° from the Sun, which is in Taurus at this time of year.
