The Moon and M44 will make a close approach, passing within a mere 33.2 arcminutes of each other. The Moon will be 12 days old.

From Fairfield , the pair will be visible in the evening sky, becoming accessible around 18:33 (EDT), 34° above your eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 22:35, 68° above your southern horizon. They will continue to be observable until around 04:16, when they sink below 16° above your western horizon.

The Moon will be at mag -12.7; and M44 will be at mag 3.1. Both objects will lie in the constellation Cancer.

They will be a little too widely separated to fit comfortably within the field of view of a telescope, but will 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 pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 08h41m10s 20°11'N Cancer -12.7 31'38"3
M44 08h40m20s 19°40'N Cancer 3.1 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 157° from the Sun, which is in Aquarius at this time of year.

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
