Conjunction of the Moon and Jupiter

The Moon and Jupiter will share the same right ascension, with the Moon passing 4°16' to the north of Jupiter. The Moon will be 22 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 23:41 (EST) and reaching an altitude of 69° above the southern horizon before fading from view as dawn breaks at around 06:42.

The Moon will be at mag -11.9, and Jupiter at mag -2.2, both in the constellation Gemini.

The pair will be too widely separated to fit 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 07h41m20s 25°43'N Gemini -11.9 31'36"7
Jupiter 07h41m20s 21°26'N Gemini -2.2 37"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 87° from the Sun, which is in Virgo at this time of year.
