Conjunction of the Moon and Jupiter

The Moon and Jupiter will share the same right ascension, with the Moon passing 5°02' to the north of Jupiter. The Moon will be 25 days old.

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 03:27 (EST) – 2 hours and 19 minutes before the Sun – and reaching an altitude of 19° above the south-eastern horizon before fading from view as dawn breaks at around 05:28.

The Moon will be at mag -11.3, and Jupiter at mag -2.2, both in the constellation Aquarius.

The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.

A graph of the angular separation between the Moon and Jupiter 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
The Moon 22h14m10s 6°44'S Aquarius -11.3 32'33"5
Jupiter 22h14m10s 11°46'S Aquarius -2.2 35"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 61° from the Sun, which is in Aries at this time of year.
