The Moon and M45 will make a close approach, passing within a mere 30.9 arcminutes of each other. The Moon will be 7 days old.

From Columbus , the pair will become visible at around 18:49 (EST), 73° above your southern horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 02:05.

The Moon will be at mag -12.0; 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 03h48m00s 23°36'N Taurus -12.0 31'16"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 92° from the Sun, which is in Capricornus 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.
