The Moon and Venus will share the same right ascension, with the Moon passing 3°44' to the south of Venus. The Moon will be 1 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 19:36 (PDT) as the dusk sky fades, 10° above your western horizon. They will then sink towards the horizon, setting 1 hour and 27 minutes after the Sun at 20:42.

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 -8.4 in the constellation Cetus, and Venus at mag -3.9 in the neighbouring constellation of Pisces.

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.

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

The positions of the two objects at the moment of conjunction will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 00h54m30s +01°03' Cetus -8.4 31'05"8
Venus 00h54m30s +04°48' Pisces -3.9 10"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 15° from the Sun, which is in Pisces at this time of year.

Warning

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.
