The Moon and M45 will make a close approach, passing within 0°58' of each other. The Moon will be 20 days old.

From Ashburn, the pair will be visible in the morning sky, becoming accessible around 22:49, when they rise to an altitude of 7° above your north-eastern horizon. They will then reach its highest point in the sky at 05:32, 75° above your southern horizon. They will be lost to dawn twilight around 06:33, 70° above your south-western horizon.

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 -12.3; and M45 will be at mag 1.3. Both objects will lie in the constellation Taurus.

They 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 through a pair of binoculars.

A graph of the angular separation between the Moon and M45 around the time of closest approach is available here.

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

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 03h46m20s +25°02' Taurus -12.3 32'27"7
M45 03h47m30s +24°06' Taurus 1.3 109'59"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 109° from the Sun, which is in Leo at this time of year.
