The Moon and M45 will make a close approach, passing within a mere 28.4 arcminutes of each other. The Moon will be 7 days old.

From Fairfield , the pair will become visible at around 18:27 (EST), 63° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 00:27.

The Moon will be at mag -11.6; 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 03h47m00s 24°34'N Taurus -11.6 30'50"4
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 77° 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.
