Conjunction of the Moon and Jupiter

The Moon and Jupiter will share the same right ascension, with the Moon passing 5°43' to the south of Jupiter. The Moon will be 16 days old.

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

From South El Monte , the pair will be visible between 20:59 and 05:23. They will become accessible at around 20:59, when they rise to an altitude of 7° above your south-eastern horizon. They will reach their highest point in the sky at 01:11, 34° above your southern horizon. They will become inaccessible at around 05:23 when they sink below 7° above your south-western horizon.

The Moon will be at mag -12.5, and Jupiter at mag -2.6, both in the constellation Ophiuchus.

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 16h56m40s 27°39'S Ophiuchus -12.5 30'03"1
Jupiter 16h56m40s 21°56'S Ophiuchus -2.6 44"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 172° from the Sun, which is in Taurus at this time of year.
