Conjunction of the Moon and Jupiter

The Moon and Jupiter will share the same right ascension, with the Moon passing 45' 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 Fairfield , the pair will be visible in the dawn sky, rising at 02:11 (EST) – 3 hours and 10 minutes before the Sun – and reaching an altitude of 30° above the eastern horizon before fading from view as dawn breaks at around 05:01.

The Moon will be at mag -10.8, and Jupiter at mag -2.2, both in the constellation Aries.

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

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 03h18m30s 18°00'N Aries -10.8 31'24"5
Jupiter 03h18m30s 17°15'N Aries -2.2 34"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 50° from the Sun, which is in Gemini at this time of year.
