The Moon and M45 will make a close approach, passing within a mere 9.7 arcminutes of each other. The Moon will be 25 days old.

From Fairfield , the pair will be visible in the dawn sky, rising at 01:21 (EDT) and reaching an altitude of 34° above the eastern horizon before fading from view as dawn breaks at around 04:42.

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 -11.0; and M45 will be at mag 1.3. Both objects will lie in the constellation Taurus.

They will be close enough to fit within the field of view of a telescope, but will also 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 03h47m20s 24°15'N Taurus -11.0 30'59"6
M45 03h47m30s 24°06'N Taurus 1.3 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 55° from the Sun, which is in Gemini at this time of year.
