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

From London (click to change), the pair will become visible at around 17:10 (BST) as the dusk sky fades, 32° above your south-western horizon. They will then sink towards the horizon, setting 4 hours and 24 minutes after the Sun at 21:10.

At the moment of closest approach, the Moon will be at mag -10.7, and Venus at mag -5.4, both in the constellation 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.

The precise positions of the Moon and Venus at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 23h52m10s -03°09' Pisces -10.7 31'37"5
Venus 23h47m30s +00°32' Pisces -5.4 30"7

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