Conjunction of the Moon and Jupiter

The Moon and Jupiter will share the same right ascension, with the Moon passing 4°29' 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 South El Monte , the pair will be visible in the morning sky, becoming accessible around 22:52, when they reach an altitude of 7° above your eastern horizon. They will then reach their highest point in the sky at 04:57, 72° above your southern horizon. They will be lost to dawn twilight around 06:16, 64° above your south-western horizon.

The Moon will be at mag -12.2, and Jupiter at mag -2.3, both in the constellation Leo.

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 09h22m20s 20°32'N Leo -12.2 31'24"5
Jupiter 09h22m20s 16°03'N Leo -2.3 39"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 107° from the Sun, which is in Scorpius at this time of year.
