Conjunction of the Moon and Jupiter

The Moon and Jupiter will share the same right ascension, with the Moon passing 50' to the north of Jupiter. The Moon will be 10 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 evening sky, becoming accessible around 20:44 (EDT), 34° above your southern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 21:25, 35° above your southern horizon. They will continue to be observable until around 01:53, when they sink below 7° above your south-western horizon.

The Moon will be at mag -12.4, and Jupiter at mag -2.4, both in the constellation Libra.

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 14h24m50s 12°14'S Libra -12.4 30'39"6
Jupiter 14h24m50s 13°05'S Libra -2.4 41"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 130° from the Sun, which is in Taurus at this time of year.
