Venus and M44 will make a close approach, passing within 0°33' of each other.

From London (click to change), the pair will be difficult to observe as they will appear no higher than 19° above the horizon. They will become visible at around 21:45 (GMT) as the dusk sky fades, 19° above your western horizon. They will then sink towards the horizon, setting 2 hours and 56 minutes after the Sun at 00:11.

At the moment of closest approach, Venus will be at mag -5.1, and M44 at mag 3.7, both in the constellation Cancer.

The pair will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible to the naked eye or a through pair of binoculars.

The precise positions of Venus and M44 at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Venus 08h40m50s +20°30' Cancer -5.1 25"5
M44 08h40m00s +19°58' Cancer 3.7 95'00"0

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