Conjunction of the Moon and Jupiter

The Moon and Jupiter will share the same right ascension, with the Moon passing 2°02' to the south of Jupiter. The Moon will be 19 days old.

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

From Columbus , the pair will be visible in the morning sky, becoming accessible around 22:21, when they reach an altitude of 7° above your eastern horizon. They will then reach their highest point in the sky at 04:37, 67° above your southern horizon. They will be lost to dawn twilight around 07:20, 48° above your western horizon.

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

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 09h05m10s 15°15'N Cancer -12.4 32'07"9
Jupiter 09h05m10s 17°17'N Cancer -2.4 41"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 120° from the Sun, which is in Ophiuchus at this time of year.
