Venus and M45 will make a close approach, passing within 2°34' of each other.

From London (click to change), the pair will become visible at around 20:11 (GMT) as the dusk sky fades, 30° above your western horizon. They will then sink towards the horizon, setting 4 hours and 3 minutes after the Sun at 23:51.

At the moment of closest approach, Venus will be at mag -4.5, and M45 at mag 1.6, both in the constellation Taurus.

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 Venus and M45 at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Venus 03h50m20s +21°38' Taurus -4.5 14"6
M45 03h47m30s +24°07' Taurus 1.6 110'00"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 38° from the Sun, which is in Pisces at this time of year.
