The Moon, Jupiter and Neptune will make a close approach, passing within 3°49' of each other. The Moon will be 5 days old.

From San Diego , the trio will become visible at around 17:03 (PDT), 38° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 20:58.

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 -10.9; Jupiter will be at mag -2.2; and Neptune will be at mag 7.9. The trio will lie in the constellation Capricornus.

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 trio 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 trio at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 21h40m50s 10°51'S Capricornus -10.9 29'27"8
Jupiter 21h47m10s 14°21'S Capricornus -2.2 34"9
Neptune 21h46m10s 13°52'S Capricornus 7.9 2"2

The coordinates above are given in J2000.0. The trio will be at an angular separation of 54° from the Sun, which is in Sagittarius at this time of year.
