The Moon and Jupiter will make a close approach, passing within 2°39' of each other. The Moon will be 22 days old.

From Fairfield , the pair will be visible in the dawn sky, rising at 23:37 (EST) and reaching an altitude of 60° above the south-eastern horizon before fading from view as dawn breaks at around 05:33.

The Moon will be at mag -11.9; and Jupiter will be at mag -2.5. Both objects will lie in the constellation Aries.

They 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 pair 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 pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 02h43m40s 17°20'N Aries -11.9 31'13"9
Jupiter 02h47m50s 14°52'N Aries -2.5 39"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 91° from the Sun, which is in Cancer at this time of year.
