Close approach of the Moon and M44

Friday 7th Jun 201907:01

The Moon and M44 will make a close approach, passing within 0°28' of each other. The Moon will be 4 days old.

From London, the pair will become visible at around 21:38 (BST) as the dusk sky fades, 24° above your western horizon. They will then sink towards the horizon, setting 3 hours and 24 minutes after the Sun at 00:33.

The Moon will be at mag -10.9, and M44 at mag 3.1, both in the constellation Cancer.

The pair will be close enough to fit within the field of view of a telescope, but will also be visible through a pair of binoculars.

A graph of the angular separation between the Moon and M44 around the time of closest approach is available here.

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

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 08h40m40s +20°08' Cancer -10.9 32'23"7
M44 08h40m20s +19°40' Cancer 3.1 95'00"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 51° from the Sun, which is in Taurus at this time of year.
