The Moon and Venus will make a close approach, passing within 5°52' of each other. The Moon will be 3 days old.

From Seattle, the pair will be difficult to observe as they will appear no higher than 10° above the horizon. They will become visible around 20:44 (PDT) as the dusk sky fades, 10° above your western horizon. They will then sink towards the horizon, setting 1 hour and 26 minutes after the Sun at 21:48.

The Moon will be at mag -10.7; and Venus will be at mag -4.3. Both objects will lie in the constellation Virgo.

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 pair will also share the same right ascension – called a conjunction.

A graph of the angular separation between the Moon and Venus around the time of closest approach is available here.

The positions of the pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 12h33m40s +01°24' Virgo -10.7 32'09"6
Venus 12h25m30s -04°06' Virgo -4.3 23"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 45° from the Sun, which is in Leo at this time of year.
