The Moon and Jupiter will make a close approach, passing within 3°17' of each other. The Moon will be 4 days old.
From Fairfield, the pair will be difficult to observe as they will appear no higher than 16° above the horizon. They will become visible around 19:54 (EST) as the dusk sky fades, 16° above your south-western horizon. They will then sink towards the horizon, setting 1 hour and 58 minutes after the Sun at 21:33.
The Moon will be at mag -10.7, and Jupiter at mag -1.8, both in the constellation Virgo.
The pair 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 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 | 13h22m10s | -03°54' | Virgo | -10.7 | 30'34"6 |
| Jupiter | 13h17m50s | -07°01' | Virgo | -1.8 | 31"7 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 48° from the Sun, which is in Leo at this time of year.
