The Moon and Jupiter will make a close approach, passing within 3°34' of each other. The Moon will be 25 days old.

From Fairfield , the pair will be visible in the dawn sky, rising at 02:03 (EST) – 3 hours and 17 minutes before the Sun – and reaching an altitude of 32° above the eastern horizon before fading from view as dawn breaks at around 05:00.

The Moon will be at mag -11.1; and Jupiter will be at mag -2.2. Both objects will lie in the constellation Aries.

They will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.

At around the same time, the pair will also share the same right ascension – called a conjunction.

A graph of the angular separation between the Moon and Jupiter 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 02h47m50s 11°16'N Aries -11.1 32'29"1
Jupiter 02h43m50s 14°43'N Aries -2.2 35"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 56° 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.
