The Moon and Jupiter will make a close approach, passing within 0°37' of each other. The Moon will be 22 days old.

From Fairfield, the pair will be visible in the dawn sky, rising at 23:07 (EST) and reaching an altitude of 69° above the south-eastern horizon before fading from view as dawn breaks around 06:08.

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 -11.8, and Jupiter at mag -2.4, both in the constellation Taurus.

The pair will be a little too widely separated to fit comfortably 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 04h55m40s +21°11' Taurus -11.8 29'36"5
Jupiter 04h55m40s +21°48' Taurus -2.4 39"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 90° from the Sun, which is in Leo at this time of year.
