The Moon and Neptune will make a close approach, passing within a mere 15.6 arcminutes of each other. The Moon will be 22 days old.

From Fairfield, the pair will be visible in the dawn sky, rising at 00:27 (EST) and reaching an altitude of 43° above the south-eastern horizon before fading from view as dawn breaks around 04:59.

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 -12.1; and Neptune will be at mag 7.9. Both objects will lie in the constellation Pisces.

They will be close enough to fit within the field of view of a telescope, but will also be visible through a pair of binoculars.

A graph of the angular separation between the Moon and Neptune 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 00h00m00s -01°06' Pisces -12.1 32'19"3
Neptune 00h00m30s -01°20' Pisces 7.9 2"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 97° from the Sun, which is in Gemini 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.
