Conjunction of the Moon and Jupiter

From the Conjunctions feed


The Moon and Jupiter will share the same right ascension, with the Moon passing 4°27' to the south of Jupiter. The Moon will be 27 days old.

From South El Monte , the pair will be visible in the dawn sky, rising at 05:15 (PDT) – 1 hour and 19 minutes before the Sun – and reaching an altitude of 10° above the south-eastern horizon before fading from view as dawn breaks at around 06:18.

The Moon will be at mag -9.5, and Jupiter at mag -1.9, both in the constellation Capricornus.

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 20h20m00s 24°21'S Capricornus -9.5 30'34"4
Jupiter 20h20m00s 19°53'S Capricornus -1.9 32"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 27° from the Sun, which is in Aquarius at this time of year.
