The Moon and Jupiter will make a close approach, passing within 3°44' of each other. The Moon will be 14 days old.

From Cambridge, the pair will be visible between 20:13 and 04:59. They will become accessible around 20:13, when they rise to an altitude of 7° above your south-eastern horizon. They will reach its highest point in the sky at 00:38, 33° above your southern horizon. They will become inaccessible around 04:59 when they sink below 8° above your south-western horizon.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

The Moon will be at mag -12.7 in the constellation Aquarius, and Jupiter at mag -2.9 in the neighbouring constellation of 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.

At around the same time, the two objects will also share the same right ascension – called a conjunction.

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 closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 22h02m10s -17°17' Aquarius -12.7 31'33"4
Jupiter 21h57m00s -13°45' Capricornus -2.9 48"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 174° from the Sun, which is in Leo at this time of year.
