The Moon, Jupiter, 134340 Pluto and Uranus will make a close approach, passing within 6°30' of each other. The Moon will be 15 days old.
From Cambridge , the quartet will be visible between 19:23 and 05:40. They will become accessible at around 19:23, when they rise to an altitude of 7° above your eastern horizon. They will reach their highest point in the sky at 00:31, 45° above your southern horizon. They will become inaccessible at around 05:40 when they sink below 7° above your western horizon.
The Moon will be at mag -12.5; Jupiter will be at mag -2.9; 134340 Pluto will be at mag 0.0; and Uranus will be at mag 5.7. 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 | 23h44m20s | 3°40'N | Pisces | -12.5 | 29'29"6 |
| Jupiter | 23h55m10s | 2°15'S | Pisces | -2.9 | 48"7 |
| 134340 Pluto | 00h00m00s | 0°00'N | Pisces | 0.0 | 0"0 |
| Uranus | 23h55m20s | 1°21'S | Pisces | 5.7 | 3"6 |
The coordinates above are given in J2000.0. The quartet will be at an angular separation of 174° from the Sun, which is in Virgo at this time of year.
