The Moon and Jupiter will make a close approach, passing within 2°33' of each other. The Moon will be 7 days old.

From Ashburn, the pair will become visible at around 20:56 (EDT) as the dusk sky fades, 41° above your south-western horizon. They will then sink towards the horizon, setting 4 hours and 39 minutes after the Sun at 01:14.

The Moon will be at mag -11.9, and Jupiter at mag -2.1, 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 12h55m40s -01°46' Virgo -11.9 30'16"7
Jupiter 12h52m20s -04°11' Virgo -2.1 36"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 94° from the Sun, which is in Gemini at this time of year.
