The Moon, Jupiter, 134340 Pluto and Uranus will make a close approach, passing within 6°35' of each other. The Moon will be 20 days old.

From Fairfield , the quartet will be visible in the morning sky, becoming accessible around 23:18, when they reach an altitude of 7° above your eastern horizon. They will then reach their highest point in the sky at 04:35, 48° above your southern horizon. They will be lost to dawn twilight around 05:25, 47° above your southern horizon.

The Moon will be at mag -12.2; Jupiter will be at mag -2.7; 134340 Pluto will be at mag 0.0; and Uranus will be at mag 5.9. The quartet will lie in the constellation Pisces.

They will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.

At around the same time, the quartet 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 quartet at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 00h03m00s 5°57'N Pisces -12.2 29'34"5
Jupiter 00h13m50s 0°03'S Pisces -2.7 44"6
134340 Pluto 00h00m00s 0°00'N Pisces 0.0 0"0
Uranus 00h01m40s 0°37'S Pisces 5.9 3"4

The coordinates above are given in J2000.0. The quartet will be at an angular separation of 124° from the Sun, which is in Cancer at this time of year.
